PSC provides 2 interrupt vectors:
Table 17-7.
Registers are explained for PSC module 0. They are identical for module 1 and module 2.
Bit
Read/Write
Initial Value
• Bit 7:6 – Res: Reserved
These bits are reserved and will always read as zero.
• Bit 5 – POEN2B: PSC Output 2B Enable
When this bit is clear, I/O pin affected to PSCOUT2B acts as a standard port.
