Resets, Interrupts, and General System Control
7.7.14
This register controls operation of the CLKOUT pin. The CS field in this register controls the output mux
function for the CLKOUT pin. The various clock sources must be enabled/disabled via the appropriate
controls elsewhere in the device.
7.7.15
This register configures connections to select peripherals. The fields in this register control clock sources
for a number of on-chip timers. The various clock sources must be enabled/disabled via the appropriate
controls elsewhere in the device.
