3.4.1Peripheral Lock Register Description

When written with correct 32 bit key (0x0F0A0B00), the Peripheral Lock Register (PERLOCK) allows one write to the PERCFG0 register within 16 SYSCLK3 cycles.

NOTE

The instructions that write to the PERLOCK and PERCFG0 registers must be in the same fetch packet if code is being executed from external memory. If the instructions are in different fetch packets, fetching the second instruction from external memory may stall the instruction long enough such that PERCFG0 register will be locked before the instruction is executed.
