SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
Preliminary Specifications REV. E
Specifications in this manual are tentative and subject to change
Timer A
Figure 1.64: Timer Ai mode register in event counter mode, single signal
Table 1.19 shows the Timer specification in event counter mode when processing two-phase signal with timers
A2, A3, and A4.
Figure 1.65 shows Timer Ai mode register in event counter mode when processing two-phase signal.
Note 1: In event counter mode, the count source is selected by the event / trigger select bit
(addresses 0382
16
and 0383
16
).
Note 2: The settings of the corresponding port register and port direction register are invalid.
Note 3: Valid only when counting an external signal.
Note 4: When an “L” signal is input to the TAi
OUT
pin, the downcount is activated. When “H”,
the upcount is activated. Set the corresponding port direction register to “0”.
Note 5: This value can be indeterminate when the count starts.
