Bit Field Type Reset Description

31-11 RESERVED R X

Software should not rely on the value of a reserved. Writing any

other value than the reset value may result in undefined behavior.

10 RFCTRC R/W X

Enable clock to the RF Core Tracer (RFCTRC) module.

9 FSCA R/W X

Enable clock to the Frequency Synthesizer Calibration Accelerator

(FSCA) module.

8 PHA R/W X

Enable clock to the Packet Handling Accelerator (PHA) module.

7 RAT R/W X

Enable clock to the Radio Timer (RAT) module.

6 RFERAM R/W X

Enable clock to the RF Engine RAM module.

5 RFE R/W X

Enable clock to the RF Engine (RFE) module.

4 MDMRAM R/W X

Enable clock to the Modem RAM module.

3 MDM R/W X

Enable clock to the Modem (MDM) module.

2 CPERAM R/W X

Enable clock to the Command and Packet Engine (CPE) RAM

module. As part of RF Core initialization, set this bit together with

CPE bit to enable CPE to boot.

1 CPE R/W X

Enable processor clock (hclk) to the Command and Packet Engine

(CPE). As part of RF Core initialization, set this bit together with

CPERAM bit to enable CPE to boot.

0 RFC R 1h

Enable essential clocks for the RF Core interface. This includes the

interconnect, the radio doorbell DBELL command interface, the

power management (PWR) clock control module, and bus clock

(sclk) for the CPE. To remove possibility of locking yourself out from

the RF Core, this bit can not be cleared. If you need to disable all

clocks to the RF Core, see the PRCM:RFCCLKG.CLK_EN register.
