Chapter 3 Modes of Operation
TPM — When the MCU enters stop mode, the clock to the TPM1 and TPM2 modules stop. The modules
halt operation. If the MCU is configured to go into stop2 mode, the TPM modules will be reset upon
wake-up from stop and must be reinitialized.
ADC — When the MCU enters stop mode, the ADC will enter a low-power standby state unless the
asynchronous clock source, ADACK, is enabled. Conversions can occur in stop3 if ADACK is enabled.
If the MCU is configured to go into stop2 mode, the ADC will be reset upon wake-up from stop and must
be re-initialized.
KBI — During stop3, the KBI pins that are enabled continue to function as interrupt sources that are
capable of waking the MCU from stop3. The KBI is disabled in stop2 and must be reinitialized after
waking up.
SCI — When the MCU enters stop mode, the clocks to the SCI1 and SCI2 modules stop. The modules
halt operation. If the MCU is configured to go into stop2 mode, the SCI modules will be reset upon
wake-up from stop and must be reinitialized.
SPI — When the MCU enters stop mode, the clocks to the SPI module stop. The module halts operation.
If the MCU is configured to go into stop2 mode, the SPI module will be reset upon wake-up from stop and
must be reinitialized.
IIC — When the MCU enters stop mode, the clocks to the IIC module stops. The module halts operation.
If the MCU is configured to go into stop2 mode, the IIC module will be reset upon wake-up from stop and
must be reinitialized.
Voltage Regulator — The voltage regulator enters a low-power standby state when the MCU enters either
of the stop modes unless the LVD is enabled in stop mode or BDM is enabled.
