3.4.2 Peripheral Configuration Register 0 Description
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 that the PERCFG0 register is locked before the instruction is
executed.

Bit Field Value Description
31:30 SRIOCTL Mode control for SRIO. SRIO does not have a corresponding status bit in the Peripheral Status
Registers. Once SRIOCTL is set to 11b, the SRIO peripheral can be used within 16 SYSCLK3
cycles.
00b Set SRIO to disabled mode
11b Set SRIO to enabled mode

22 UTOPIACTL Mode control for UTOPIA
0 Set UTOPIA to disabled mode
1 Set UTOPIA to enabled mode

0 Set PCI to disabled mode
1 Set PCI to enabled mode
19 Reserved Reserved.
18 HPICTL Mode control for HPI. This bit defaults to 1 when host boot is used (BOOTMODE[3:0] = 0001b).
0 Set HPI to disabled mode
