PSC Output Compare SA Register – POCRnSAH and POCRnSAL
PSC Output Compare RA Register – POCRnRAH and POCRnRAL
PSCOutput Compare SB Register – POCRnSBH and POCRnSBL
PSC Output Compare RB Register – POCR_RBH and POCR_RBL
PSC Configuration Register – PCNF
Note:
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 16bit 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.
• Bit 7:6 - not use
not use
• Bit 5 – PULOCK: PSC Update Lock
When this bit is set, the Output Compare Registers POCRnRA, POCRnSA, POCRnSB,
POCR_RB and the PSC Output Configuration Registers POC can be written without disturb-
ing the PSC cycles. The update of the PSC internal registers will be done if the PULOCK bit is
released to zero.
