4.3.2.2 AUTOVECTOR REGISTER (AVR). The AVR contains bits that correspond to
external interrupt levels that require an autovector response. Setting a bit allows the
SIM40 to assert an internal AVEC during the IACK cycle in response to the specified
interrupt request level. This register can be read and written at any time.
4.3.2.3 RESET STATUS REGISTER (RSR). The RSR contains a bit for each reset source
to the SIM40. A set bit indicates the last type of reset that occurred, and only one bit can
be set in the register. The RSR is updated by the reset control logic when the SIM40
comes out of reset. This register can be read at any time; a write has no effect. For more
information, see Section 3 Bus Operation.
EXT—External Reset
POW—Power-Up Reset
SW—Software Watchdog Reset
DBF—Double Bus Fault Monitor Reset
Bits 3, 0—Reserved
MOTOROLA
value of $0 prevents arbitration and causes all SIM40 interrupts, including external
interrupts, to be discarded as extraneous.
1 = The last reset was caused by an external signal driving RESET .
1 = The last reset was caused by the power-up reset circuit.
1 = The last reset was caused by the software watchdog circuit.
1 = The last reset was caused by the double bus fault monitor.
The IARB field in the MCR must contain a value other than $0
for the SIM40 to autovector for external interrupts.
