Notes: 1. Not initialized in deep standby mode. But initialized after deep standby mode is
released because a power-on reset exception handling is executed.
2. Initialized by UDTRST assertion or in the Test-Logic-Reset state of the TAP controller.
3. Bits BN[3:0] are initialized.
4. Retains the previous value after an internal power-on reset by means of the WDT.
5. Counting up continues.
6. Bits RTCEN and START are retained.
7. Bits BC[3:0] are initialized.
