RA001

Note 1: The auto capture can be used only in the timer, event counter, external trigger timer and window modes.

Note 2: Set TA0TFF, TA0OVE and TA0NC in the stopped state (TA0S="0"). Writing is invalid during the operation (TA0S="1").

Note 3: When the STOP mode is started, the start control (TA0S) is automatically cleared to "0" and the timer stops. Set TA0S

again to use the timer counter after the release of the STOP mode.

Note 4: When a read instruction is executed on TA0CR, bits 3 and 2 are read as "0".

Note 5: Do not set TA0NC to "01" or "10" when the SLOW 1/2 or SLEEP 1 mode is used. Setting TA0NC to "01" or "10" stops the

noise canceller and no signal is input to the timer.
