Note 1: Even when open-drain mode is selected, the protective diode remains connected. Therefore, do not apply voltages ex-
Note 2: Read-Modify-Write (RMW) operation executes at open-drain mode is selected, read out the output latch states.
Note 3: When using the 16-bit timer (CTC) as an ordinary timer, set P47 (CTC) for output mode.
