level according to PSCRV fuse bit. In this second case, PSCOUT20 & PSCOUT21 keep the forced state
until PSOC2 register is written.
If PSC2RBA fuse equals 1 (unprogrammed), PSCOUT22 & PSCOUT23 keep a standard port behavior. If
PSC2RBA fuse equals 0 (programmed), PSCOUT22 & PSCOUT23 are forced at reset to low level or
high level according to PSCRV fuse bit. In this second case, PSCOUT22 & PSCOUT23 keep the forced
state until PSOC2 register is written.

PSC Input Behavior During Reset
For power consumption under reset reason, the state of PSC & PSCR inputs during Reset can be pro-
grammed by fuse PSCINRB.
If PSCINRB fuse equals 1 (unprogrammed), PSC & PSCR input keep a standard port behavior. If
PSCINRB fuse equals 0 (programmed), PSC & PSCR input pull-up are forced while the reset is active.
Affected pins are PSCIN2, PSCINr, PSCIN2A, PSCINrA. To prevent any conflict on PD1, this fuse has
no effect on PSCINrB.
