Reset States
Pin reset occurs if the RSTB pin is asserted (low). (See
RSTB Pin Reset on page 18
for more information.) Tables
74
through
77
describe how reset affects the state of the core registers.
Table 78 on page 114
describes how reset
affects the state of the peripheral (off-core) registers. The following bit codes apply:
Bit code
indicates that this bit is unknown after powerup reset and is unaffected by subsequent pin resets.
Bit code
P
indicates the value on the corresponding input pin (applies to
sbit
register and the IOBIT[7:0] pins).

resets to 0x20000 (first address of IROM) if the EXM pin is 0 at the time of reset. It resets to 0x80000 (first
address of EROM) if the EXM pin is 1 at the time of reset.
