MPU_enablePUCOnViolation()

MPU_enablePUCOnViolation	(	MPU_BASE	,
		MPU_SECOND_SEG
	)

MSP430FR57x Demo - MPU Write protection violation - PUC in the device's boot process. The MPU configuration code is put in the _system_pre_init() for CCS and __low_level_init() for IAR.

Description: The MPU segment boundaries are defined by: Border 1 = 0xCA00 [segment #: 5] Border 2 = 0xD000 [segment #: 8] Segment 1 = 0xC200 - 0xC9FF Segment 2 = 0xCA00 - 0xCFFF Segment 3 = 0xD000 - 0xFFFF Segment 2 is write protected. Any write to an address in the segment 2 range causes a PUC. The LEDs toggles due to repeated PUCs. A delay is included so the debugger can gain access via JTAG.

ACLK = n/a, MCLK = SMCLK = TACLK = default DCO = ~625 KHz
