Table 10-7. Clock IO Config (CLKIOCR) [0x32] [R/W]
10.2 CPU Clock During Sleep Mode
When the CPU enters sleep mode the CPUCLK Select (Bit [0],
oscillator is stopped. When the CPU comes out of sleep mode it runs on the internal oscillator. The internal oscillator recovery time is
three clock cycles of the Internal 32 kHz Low power Oscillator.
If the system requires the CPU to run off the external clock after awaking from sleep mode, the firmware must switch the clock source
for the CPU.
