PSC Output Behavior During Reset
PSC Input Behavior During Reset
Table 21-4.
Notes:
For external component safety reason, the state of PSC outputs during Reset can be programmed by fuses
PSCRV, PSCRRB & 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 & 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 PSCRRB fuse equals 1 (unprogrammed), PSCOUTR0 & PSCOUTR1 keep a standard port behavior. If
PSC0RB fuse equals 0 (programmed), PSCOUTR0 & PSCOUTR1 are forced at reset to low level or high
level according to PSCRV fuse bit. In this second case, PSCOUTR0 & PSCOUTR1 keep the forced state
until PSOC0 register is written.
If PSC2RB fuse equals 1 (unprogrammed), PSCOUT20 & PSCOUT21 keep a standard port behavior. If
PSC2RB fuse equals 0 (programmed), PSCOUT20 & PSCOUT21 are forced at reset to low level or high
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.
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.
