Functional Description The members of the SAB 80515 family of microcontrollers are: – SAB 80C515: Microcontroller, designed in Siemens ACMOS technology, with 8 Kbyte factory mask-programmable ROM – SAB 80C535: ROM-less version of the SAB 80C515 – SAB 80515: Microcontroller, ...
Page 16
CPU The SAB 80C515 is efficient both as a controller and as an arithmetic processor. It has extensive facilities for binary and BCD arithmetic and excels in its bit-handling capabilities. Efficient use of program memory results from an instruction set ...

I/O Ports The SAB 80C515 has six 8-bit I/O ports and one 8-bit input port. Port open-drain bidirectional I/O port, while ports are quasi-bidirectional I/O ports with internal pullup resistors. That means, when configured ...
Page 24
Timer/Counters The SAB 80C515 contains three 16-bit timers/counters which are useful in many applications for timing and counting. The input clock for each timer/counter is 1/12 of the oscillator frequency in the timer operation or can be taken from an ...
Page 25
Compare In the compare mode, the 16-bit values stored in the dedicated compare registers are compared to the contents of the timer 2 registers. If the count value in the timer 2 registers matches one of the stored values, an ...
Page 26
Serial Port The serial port of the SAB 80C515 enables full duplex communication between microcontrol- lers or between microcontroller and peripheral devices. The serial port can operate in 4 modes: Mode 0: Shift register mode. Serial data enters and exits ...

Watchdog Timer This feature is provided as a means of graceful recovery from a software upset. After an external reset, the watchdog timer is cleared and stopped. It can be started and cleared by software, but it cannot be stopped ...
Page 32
If the power-down mode and the idle mode are set at the same time, power-down takes prece- dence. Furthermore, register PCON contains two general purpose flags. For example, the flag bits GF0 and GF1 can be used to give an ...
Page 33
If all timers are stopped and the A/D converter and the serial interface are not running, the maximum power reduction can be achieved. This state is also the test condition for the idle mode I (see DC characteristics, note 5). ...
Page 34
When idle mode is used, pin PE must be held on low level. The idle mode is then entered by two consecutive instructions. The first instruction sets the flag bit IDLE (PCON.0) and must not set bit IDLS (PCON.5), the ...
Page 35
Note that PCON is not a bit-addressable register, so the above mentioned sequence for entering the power-down mode is obtained by byte-handling instructions, as shown in the following example: ORL PCON,#00000010 ORL PCON,#01000000 The instruction that sets bit PDS is ...
