14.4. Suspend Mode
Setting the Suspend Mode Select bit (PMU0CF.6) causes the system clock to be gated off and all internal
oscillators disabled. The system clock source must be set to the low power internal oscillator or the preci-
sion oscillator prior to entering suspend mode. All digital logic (timers, communication peripherals, inter-
rupts, CPU, etc.) stops functioning until one of the enabled wake-up sources occurs.
The following wake-up sources can be configured to wake the device from Suspend Mode:
Note: Upon wake-up from suspend mode, PMU0 requires two system clocks in order to update the PMU0CF
In addition, a noise glitch on RST that is not long enough to reset the device will cause the device to exit
suspend. In order for the MCU to respond to the pin reset event, software must not place the device back
into suspend mode for a period of 15 µs. The PMU0CF register may be checked to determine if the wake-
up was due to a falling edge on the /RST pin. If the wake-up source is not due to a falling edge on RST,
there is no time restriction on how soon software may place the device back into suspend mode. A 4.7 kW
pullup resistor to VDD_MCU/DC+ is recommend for RST to prevent noise glitches from waking the device.

wake-up flags. All flags will read back a value of '0' during the first two system clocks following a wake-
up from suspend mode. One of the two internal oscillators must be selected as the system clock when
entering Suspend Mode.
