Peripheral Configuration Register 0 Description
TMS320C6454
Fixed-Point Digital Signal Processor
SPRS311A – APRIL 2006 – REVISED DECEMBER 2006
The Peripheral Configuration Register (PERCFG0) is used to change the state of the peripherals. One
write is allowed to this register within 16 SYSCLK3 cycles after the correct key is written to the PERLOCK
register.
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.
