Description

Clock Output Configuration register

Fields

CLKOUTSEL

Selects the clock source for the CLKOUT function. 0x0 = Selects the CPU clock as the CLKOUT source. 0x1 = Selects the main oscillator as the CLKOUT source. 0x2 = Selects the Internal RC oscillator as the CLKOUT source. 0x3 = Selects the USB clock as the CLKOUT source. 0x4 = Selects the RTC oscillator as the CLKOUT source. 0x5 = Selects the SPIFI clock as the CLKOUT source. 0x6 = Selects the Watchdog oscillator as the CLKOUT source. Other settings are reserved. Do not use.

CLKOUTDIV

Integer value to divide the output clock by, minus one. 0x0 = Clock is divided by 1. 0x1 = Clock is divided by 2. 0x2 = Clock is divided by 3. … 0xF = Clock is divided by 16.

CLKOUT_EN

CLKOUT enable control, allows switching the CLKOUT source without glitches. Clear to stop CLKOUT on the next falling edge. Set to enable CLKOUT.

CLKOUT_ACT

CLKOUT activity indication. Reads as 1 when CLKOUT is enabled. Read as 0 when CLKOUT has been disabled via the CLKOUT_EN bit and the clock has completed being stopped.

RESERVED

Reserved. Read value is undefined, only zero should be written.
