Notes 1. The response time is the time until the output is inverted following detection of voltage by POC, or the
time until operation stabilizes after the shift from the operation stopped state to the operating state.
2. The oscillation stabilization time is the amount of time the CPU operation is stopped in order to avoid
unstable operation at the start of oscillation. Program operation does not start until both the oscillation
stabilization time and the time until oscillation starts have elapsed.
3. 2
15/fX or 217/fX can be selected using the mask option (refer to 9. MASK OPTION).
4. 2
12/fX, 215/fX, or 217/fX can be selected using bits 0 to 2 (OSTS0 to OSTS2) of the oscillation stabilization
time selection register (OSTS) (refer to 7.2 Standby Function Control Register).
