Reserved—write with zero.
Power up the SSIO (enable the SSIO clock).
Power down SSIO (disable the SSIO clock).
Power up the PHIF16 (enable the PHIF16 clock).
Power down PHIF16 (disable the PHIF16 clock).
Power down the ring oscillator and deselect it as the internal source
clock.
Power up the ring oscillator and select it as the internal source
clock. (Overridden by PLLSEL field (
pllc
[14])— PLLSEL = 1, then
the PLL is selected as the clock source.)
Enable internal clock operation (CLK).
Disable internal clock operation (CLK), suspending all core, periph-
eral, and I/O activity until one of the following occurs:
