Figure 6 System Configuration and Protection Block
3.2.1 System Configuration
The SIM controls MCU configuration during normal operation and during internal testing.
The SIM configuration register controls system configuration. It can be read or written at any time, ex-
cept for the module mapping (MM) bit, which can be written only once.
EXOFF —External Clock Off
0 = The CLKOUT pin is driven from an internal clock source.
1 = The CLKOUT pin is placed in a high-impedance state.
FRZSW —Freeze Software Enable
0 = When FREEZE is asserted, the software watchdog and periodic interrupt timer counters con-
tinue to run.
1 = When FREEZE is asserted, the software watchdog and periodic interrupt timer counters are dis-
abled, preventing interrupts during software debug.
FRZBM —Freeze Bus Monitor Enable
0 = When FREEZE is asserted, the bus monitor continues to operate.
1 = When FREEZE is asserted, the bus monitor is disabled.
