Enables the inter-processor communication feature.
If set, enables serial reception. Cleared by software to disable reception.
The 9 th transmitted data bit in Modes 2 and 3. Set or cleared by the MPU, depending
on the function it performs (parity check, multiprocessor communication etc.)
In modes 2 and 3 it is the 9 th data bit received. In Mode 1, if SM20 is 0, RB80 is the
stop bit. In mode 0 this bit is not used. Must be cleared by software
Transmit interrupt flag, set by hardware after completion of a serial transfer. Must be
cleared by software.
Receive interrupt flag, set by hardware after completion of a serial reception. Must
be cleared by software

Timers and Counters
The 80515 has two 16-bit timer/counter registers: Timer 0 and Timer 1. These registers can be configured for counter
or timer operations.
In timer mode, the register is incremented every machine cycle meaning that it counts up after every 12 periods of the
MPU clock signal.
