STR720 - MISCELLANEA REGISTERS (GCR - CGC - AHB_ERR)

357/401

CGC Peripheral Clock Gating register 2 (CGC-PCG2)

Address: 0xF000_2C0C

Reset value: 0x0000

This register configures clock gating for each specific clock signal used by some blocks

requiring dedicated clocks for their operations. Each dedicated clock signal is delivered to the

related peripheral only when its corresponding gating bit is cleared.

Bits 15:3 = Reserved. These bits must be always written to 0.

Bits 2:1 = DxCO: Dedicated peripheral x Clock Off

0: Peripheral x dedicated clock is gated off and the block kernel is not clocked.

1: Peripheral x dedicated clock is delivered.

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

The following table lists the correspondence between each dedicated peripheral clock and the

CGC-PCG2 register bits along with their reset value.
