Bit 1 – ENABLE: SERCOM Enable Synchronization Busy

SERCOM Enable Synchronization Busy

Enabling and disabling the SERCOM (CTRLA.ENABLE) requires synchronization. When written, the SYNCBUSY.ENABLE bit will be set until synchronization is complete.

Writes to any register (except for CTRLA.SWRST) while enable synchronization is on-going will be discarded and an APB error will be generated.

ValueDescription
0 Enable synchronization is not busy.
1 Enable synchronization is busy.

Bit 0 – SWRST: Software Reset Synchronization Busy

Software Reset Synchronization Busy

Resetting the SERCOM (CTRLA.SWRST) requires synchronization. When written, the SYNCBUSY.SWRST bit will be set until synchronization is complete.

Writes to any register while synchronization is on-going will be discarded and an APB error will be generated.

ValueDescription
0 SWRST synchronization is not busy.
1 SWRST synchronization is busy.
