STR720 - MISCELLANEA REGISTERS (GCR - CGC - AHB_ERR)

358/401

CGC Peripheral Under Reset register 2 (CGC-PUR2)

Address: 0xF000_2C10

Reset value: 0x0000

This register configures the reset line status for each of the peripheral kernels requiring a

dedicated clock. Each peripheral can be used only when its corresponding reset line is not

active.

Bit 15:2 = Reserved. These bits must be always written to 0.

Bit 1 = D1UR: Dedicated peripheral 1 Under Reset

0: Peripheral 1 is under reset.

1: Peripheral 1 is operating normally.

Bit 0 = Reserved. This bit must be always written to 0.

The following table lists the correspondence between each controlled peripheral and the

CGC-PUR2 register bits along with their reset value.
