16-BIT CMOS MICROCOMPUTER
MITSUBISHI MICROCOMPUTERS
When a phase-related pulse with a falling edge input to the TAkOUT
pin is input after the level of TAlIN pin changes from “H” to “L”, the
count is decremented at the respective rising edge and falling edge
of the TAlIN pin and TAlOUT pin. When performing this two-phase
pulse signal processing, bits 0 and 4 of timer Aj mode register must
be set to “1” and bits 1, 2, 3, and 5 must be “0”. Bits 6 and 7 are ig-
nored. (See Figure 27.) Note that bits 5, 6, and 7 of the up-down reg-
ister 0 (address 4416) are the two-phase pulse signal processing
select bits for timers A2, A3, and A4, respectively. Also, bits 5, 6, and
7 of the up-down register 1 (address C416) are the two-phase pulse
signal processing select bits for timers A7, A8, and A9, respectively.
Each timer operates in normal event counter mode when the corre-
sponding bit is “0” and performs two-phase pulse signal processing
when it is “1”.
Count is started by setting the count start bit to “1”. Data write and
read are performed in the same way as for normal event counter
mode. Note that the direction register of the input port must be set to
input mode because two kinds of pulse signals, described above,
are input. Also, there can be no pulse output in this mode.
