(1) Timer mode
Prescaler Z counts the selected count source and each time the count clock is applied, the prescaler has
its content decremented by one. After reaching “0016,” prescaler Z underflows at the next count clock and
is reloaded with the value transferred from the prescaler-Z reload register and starts counting over again.
The divide-by ratio of prescaler Z is 1 / (n + 1) where n = set value of prescaler Z.
Timer Z has its content decremented by one each time an underflow signal is received from prescaler Z.
After reaching “0016,” timer Z underflows at the next count clock and is reloaded with the value trans-
ferred from the timer-Z primary reload register and starts counting over again. (In timer mode, the timer
always counts the content of the timer Z primary reload register. The timer Z secondary is unused in this
mode.)
The divide-by ratio of timer Z is 1 / (m + 1) where m = set value of Timer Z. Therefore, assuming n = set
value of prescaler Z and m = set value of timer Z, the divide-by ratio of timer Z is 1 / ((n + 1) x (m + 1)).
In time mode, it is possible to choose whether to write to only the reload registeres of prescaler Z and
timer Z primary or both prescaler Z and timer Z and their reload registeres by setting the timer Z write
control bit.
In timer mode, an interrupt is generated by an underflow of timer Z.
(2) Programmable waveform generation mode
In programmable waveform generation mode, the microcomputer, while counting the set values of timer
Z primary and timer Z secondary alternately, outputs from the TZOUT pin a waveform whose polarity is
inverted each time timer Z underflows.
When operating in this mode, always be sure to set the timer Z write control bit to 1, thereby choosing to
write to only the reload registers. In this mode, said pin is always directed for output regardless of how the
direction register for the port P31 that is shared with the output pin is set.
The polarity of the output waveform is set by using the timer Z output level latch. If the timer Z output level
latch is set to 0, the microcomputer outputs a high for the period equal to the set value of timer Z primary
and a low for the period equal to the set value of timer Z secondary alternately. When the timer starts the
output is high at the beginning and when it stops the output returns low. If the timer Z output level latch is
set to 1, the microcomputer outputs a low for the period equal to the set value of timer Z primary and a
high for the period equal to the set value of timer Z secondary alternately. When the timer starts the
output is low at the beginning and when it stops the output returns high. If the Timer Y, Z Output Control
Register’s timer Z programmable waveform generation output switching bit is set to 1, the Port P31
Register value is output synchronously when timer Z secondary underflows.
In this mode also, the waveform output primary period and secondary period can each be extended 0.5
cycles of the count source by setting the timer Z primary waveform extension and timer Z secondary
waveform extension control bits to 1. This helps to output waveforms with higher resolution.
When using the waveform extension control bits, the frequency and duty cycle of the output waveform
become as shown below.
Waveform frequency: FZOUT=(2xTMZCL)/((2xTZPR+1)+2x(TZSC+1)+(EXPZPR+EXPZSC))
Duty: DZOUT=(2x(TZPR+1)+(EXPZPR)/((2x(TZPR+1)+EXPZPR)+(2x(TZSC+1)+EXPZSC))
TMZCL: Timer Z count source (frequency)
TZPR: Timer Z primary (8-bit)
TZSC: Timer Z secondary (8-bit)
EXPZPR: Timer Z primary waveform extension control bit (1 bit)
EXPZSC: Timer Z secondary waveform extension control bit (1 bit)
