select bit (Note 1)(Note 2) ^{1 : Multiply-by-4 processing operation}
Note 1: This bit is valid for timer A3 mode register. Timer A2 is fixed to normal processing
operation, and timer A4 is fixed to multiply-by-4 processing operation.
Note 2: When performing two-phase pulse signal processing, make sure the two-phase pulse
signal processing operation select bit (address 038416) is set to “1”. Also, always be
sure to set the event/trigger select bits (addresses 038216 and 038316) to “00”.
Note 3: Timer A2 cannot be used for two-phase pulse signal processing.
