PSC Output Behaviour During Reset
Table 25-4.
Note:
For external component safety reason, the state of PSC outputs during Reset can be pro-
grammed by fuses PSCRV, PSC0RB, PSC1RB & PSC2RB.
These fuses are located in the Extended Fuse Byte ( see
PSCRV gives the state low or high which will be forced on PSC outputs selected by PSC0RB,
PSC1RB & PSC2RB fuses.
If PSCRV fuse equals 0 (programmed), the selected PSC outputs will be forced to low state. If
PSCRV fuse equals 1 (unprogrammed), the selected PSC outputs will be forced to high state.
If PSC0RB fuse equals 1 (unprogrammed), PSCOUT00 & PSCOUT01 keep a standard port
behaviour. If PSC0RB fuse equals 0 (programmed), PSCOUT00 & PSCOUT01 are forced at
reset to low level or high level according to PSCRV fuse bit. In this second case, PSCOUT00 &
PSCOUT01 keep the forced state until PSOC0 register is written..
If PSC1RB fuse equals 1 (unprogrammed), PSCOUT10 & PSCOUT11 keep a standard port
behaviour. If PSC1RB fuse equals 0 (programmed), PSCOUT10 & PSCOUT11 are forced at
reset to low level or high level according to PSCRV fuse bit. In this second case, PSCOUT10 &
PSCOUT11 keep the forced state until PSOC1 register is written.
If PSC2RB fuse equals 1 (unprogrammed), PSCOUT20, PSCOUT21, PSCOUT22 &
PSCOUT23 keep a standard port behaviour. If PSC1RB fuse equals 0 (programmed),
PSCOUT20, PSCOUT21, PSCOUT22 & PSCOUT23 are forced at reset to low level or high
level according to PSCRV fuse bit. In this second case, PSCOUT20, PSCOUT21, PSCOUT22 &
PSCOUT23 keep the forced state until PSOC2 register is written.
