6.7.11 FAULT_CLEAR_REG: Fault Clear Register
This register allows the application to clear the current fault so that another can be captured when 1 is
written to this register.

Bit Field Value Description
31-1 Reserved 0 Reads return 0, writes have no effect.
0 FAULT_CLEAR Fault Clear
0 Read: Current value of the FAULT_CLEAR bit is 0.
Write: Writing 0 has no effect.
1 Read: Current value of the FAULT_CLEAR bit is 1.
Write: Writing a 1 clears the current fault.
6.7.12 PINMMRnn: Output Pin Multiplexing Control Registers
These registers control the output multiplexing of the functionality available on each pad on the
microcontroller. There are 38 such registers – PINMMR0 through PINMMR37. Each 8-bit field of a
PINMMR register controls the functionality of a single ball/pin. The mapping between the PINMMRx
control registers and the functionality selected on a given terminal is defined in
Table 6-1 .
