Auto Clock Gating
This bit specifies whether the system uses the Sleep-Mode Clock Gating Control (SCGCx) registers
and Deep-Sleep-Mode Clock Gating Control (DCGC) registers if the M3 CPU enters a sleep or
deep-sleep mode.
The RCGC registers are always used to control the clocks in run mode.
0 The Run-Mode Clock Gating Control (RCGCx) registers are used when the microcontroller enters a
sleep mode.
1 The SCGCx or DCGCx registers are used to control the clocks distributed to the peripherals when
the microcontroller is in a sleep mode. The SCGCx and DCGCx registers allow unused peripherals
to consume less power when the M3 CPU in a sleep mode.
