Note Bit 3 is read-only.
Cautions 1. 20 MHz internal oscillation can only be used if V
This register controls the 20 MHz internal high-speed oscillation clock (DSC) function.
It can be used to select whether to use the 20 MHz internal high-speed oscillation clock (f
hardware clock that supports 20 MHz.
DSCCTL can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
