... During this time the circuit is in RESET and the strobe output STB/RST is high. Waking up from SLEEP mode clears the SLEEP flag but not the SLmask bit. By reading SLmask one can therefore determine if the EM6603 was powered up (SLmask = 0), or woken from SLEEP mode (SLmask = 1). ...

... Reset To initialize the EM6603, a system RESET must be executed. There are four methods of doing this: (1) Initial RESET from the oscillation detection circuit. (2) External RESET from the RESET PIN. (3) External RESET by simultaneous high input to terminals PA0..PA3. (Combinations defined by metal option) (4) Watchdog RESET (software option). ...

... PortB The EM6603 has one four bit general purpose I/O port. Each bit PB(0:3) can be separately configured by software to be either input or output by writing to the corresponding bit of the CIOPortB control register. The PortB register is used to read data when in input mode and to write data when in output mode. On each terminal Pull-Up/Down resistor can be selected by metal option which are active only when selected as input ...

... PortD The EM6603 has one all purpose I/O port similar to PortC but without interrupt capability. The PortD register is used to read input data when an input and to write output data for output. The input line can be pulled Up/Down (metal option) when the port is used as input. Input mode is set by writing 0 to the I/O control bit CIOPD in register CPIOB, and the terminal becomes high impedance ...

... BUZZER The EM6603 has one 50% duty cycle output with three different frequencies which can be used to drive a buzzer. I/O terminal PB0 is used for this function when the buzzer is enabled by setting the BUen bit Table 22 below shows how to select the frequency by writing to the BCF1 and BCF0 control flags in the BEEP register ...

... Timer/Event Counter The EM6603 has a built-in 8 bit countdown auto-reload Timer/Event counter that takes an input from either the prescaler or Port PA3. If the Timer/Event counter counts down to $00 the interrupt request flag IntTim is set the Timer/Event counter interrupt is enabled by setting the mask flag MTimC set to 1, then an interrupt request is generated to the CPU ...

... Supply Voltage Level Detector The EM6603 has a software configurable built-in supply voltage level detector. Three levels can be defined between VDDmin + 100mV and VDDmax - 600mV in steps of 100mV. During SLEEP mode this function is disabled. The required voltage compare level is selected by writing the bits VLC1 and VLC2 in the SVLD control register which also activates the compare measurement ...

... Serial (Output) Write Buffer – SWB The EM6603 has a simple Serial Write Buffer (SWB) which outputs serial data and serial clock. The SWB is enabled by setting the bit V03 in the CLKSWB register as well as setting port D to output mode. The combination of the possible PortD mode is shown in Table 34. In SWB mode the serial clock is output on port D0 and the serial data is output on port D1. The signal TestVar[3], which is used by the processor to make conditional jumps, indicates " ...

... Interrupt subroutine that the STSWB bit went low before exiting interrupt. Be careful because if STSWB bit is cleared by software transmission is stopped immediately. At the end of transmission a dummy write of SWBuff must be done to clear TESTvar[3] empty interrupt" or the next transmission will not work.

... STroBe / ReSeT Output The STB/RST output pin is used to indicate the EM6603 RESET condition as well as write operations to ports B, C and D. For a PortB, PortC and PortD write operation the STROBE signal goes high for half of the system clock period. Write is effected on falling edge of the strobe signal and it can this be used to indicate when data changes at the output port pins ...
