Technical Data

OSCOUT

PC
All of these resets produce the vector $FFFE–FFFF ($FEFE–FEFF in
monitor mode) and assert the internal reset signal (IRST). IRST causes
all registers to be returned to their default values and all modules to be
returned to their reset states.
An internal reset clears the SIM counter (see
external reset does not. Each of the resets sets a corresponding bit in
the reset status register (RSR). (See
The RST pin circuit includes an internal pullup device. Pulling the
asynchronous RST pin low halts all processing. The PIN bit of the reset
status register (RSR) is set as long as RST is held low for a minimum of
67 OSCXCLK cycles, assuming that neither the POR nor the LVI was the
source of the reset. See
