B.5.2
Typically the EPROM will be programmed by the bootstrap routines resident in the on-chip ROM.
However, the user program can be used to program some EPROM locations if the proper
procedure is followed. In particular, the programming sequence must be running in RAM, as the
EPROM will not be available for code execution while the E6LAT bit is set. The V
occur externally after the E6PGM bit is set, for example under control of a signal generated on a
pin by the programming routine.
Note:
To allow simultaneous programming of up to sixteen bytes, these bytes must be in the same group
of addresses which share the same most significant address bits; only the four least significant bits
can change.
B.5.3
WOIE — Wired-OR interrupt enable bit
The WOIE bit can be used to enable the wired-OR interrupts (WOI) on the NWOI pin and on all
port B pins that have been programmed as inputs. WOI is activated if the WOIE bit is set and if the
WOI bit in the mask options register (MOR) is also set (see
WOIE is forced to zero. External and power-on resets clear the WOIE bit.
CAF — MCAN asleep flag
This flag is set by the MCU when the MCAN module enters SLEEP mode.This is the only indication
that the MCAN is asleep (see

0 (clear) –

When the part becomes a PROM, only the cumulative programming of bits to logic ‘1’
is possible if multiple programming is made on the same byte.
