Power Management Register (PMR)
Hardware watchdog timeout. This bit is set when the hardware watchdog timer has reached its
programmed timeout value. If HWTEN is also set, the bus cycle is terminated with an access error
exception.
Read protect violation. This bit is set when a read access is attempted to an area for which the chip select
is set to write only. If RPVEN is also set, the bus cycle is terminated with an access error exception.
External transfer error. This bit is set when an external transfer error is reported to the SIM on TEA. If
EXTEN is also set, the bus cycle is terminated with an access error exception.
Supervisor/user violation. This bit is set when a user mode access is attempted to an area for which the
chip select is set to supervisor only. If SUVEN is also set, the bus cycle is terminated with an access error
exception.
