... PortA The EM6607 has one 4-bit general purpose input port. Each of the input port terminals PA3..PA0 has an internal pull- Up/Down resistor, which can be selected with mask options. Port information is directly read from the pin into a register. On inputs PA0, PA1, PA2 and PA3 debouncers for noise rejection are added by default. For interrupt generation, either direct input and debounced input can be chosen ...

... PortD The EM6607 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 ...

... Timer/Event Counter The EM6607 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.

... R 12 Serial Write Buffer – SWB The EM6607 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 " ...

... LowSWB and HighSWB register together with AutoSWB bit = 1. Now everything is ready for serial transmission. To start the transmission one has to put the EM6607 in standby mode with the HALT instruction. With this serial transmission starts. When transmission is finished the TESTvar[3] (can be used for conditional jumps) becomes active High, the AutoSWB bit is cleared, the processor is leaving the Standby mode and INTEN is switched on ...

... 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] and "SWBbuffer empty interrupt" or the next transmission will not work.

... R 13 STroBe / ReSeT Output The STB/RST output pin is used to indicate the EM6607 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. In addition, any EM6607 internal RESET condition is indicated by a continuous high level on STB/RST for the period of the RESET ...
