18.16.4. PSC Output Compare RA Register
Note: n = 0 to 2 according to module number.
The Output Compare Registers RA, RB, SA and SB contain a 12-bit value that is continuously compared
with the PSC counter value. A match can be used to generate an Output Compare interrupt, or to
generate a waveform output on the associated pin.
The Output Compare Registers are 16-bit and 12-bit in size. To ensure that both the high and low bytes
are written simultaneously when the CPU writes to these registers, the access is performed using an 8-bit
temporary high byte register (TEMP). This temporary register is shared by all the other 16-bit registers.
