RW
External Control 0. The state of this bit is reflected on the XCTL0 pin. This pin is also muxed with
PCLKO. COF must be greater than 0x1011 for PCLKO to be disabled, see SS [32].

External Control 1. The state of this bit is reflected on the XCTL1 pin. XCTL1 may also be used for
Ring-In Interrupt. Open drain output, contains internal pull-up ~ 0.5 mA.
