Preliminary Specifications REV.B
Specifications in this manual are tentative and subject to change
Timer A
(4) Pulse-width modulation (PWM) mode
In this mode, the timer outputs pulses of a given width in succession. (See Table 20 .) In this mode,
the counter functions as either a 16-bit pulse-width modulator or an 8-bit pulse-width modulator.
Fig-
ure 67 shows the timer Ai mode register in pulse-width modulation mode. Figure 68 shows the exam-
ple of how a 16-bit pulse-width modulator operates. Figure 69 shows the example of how an 8-bit
pulsewidth modulator operates.

Specication
Count source
f1, f8, f32
Count operation
The timer counts down (operating as an 8-bit or a 16-bit pulse-width modulator)
The timer reloads a new count at a rising edge of PWM pulse and continues counting
The timer is not affected by a trigger that occurs when counting
16-bit PWM
High level width
n / n n : Set value
Cycle time(216-1) / xed
8-bit PWM
High level width
n
(m+1) /
n : values set to timer Ai register’s high-order address
Cycle time
(28-1)
(m+1) /
m : values set to timer Ai register’s low-order address
Count start condition
External trigger is input
The timer overows
The count start ag is set (= 1)
Count stop condition
The count start ag is reset (= 0)
Interrupt request
generation timing
PWM pulse goes “L”
TAiIN pin function
Programmable I/O port or trigger input
TAiOUT pin function
PUlse output
Read from timer
When timer Ai register is read, it indicates an indeterminate value
Write to timer
When counting stopped
When a value is written to timer Ai register, it is written to both reload register and counter
When counting in progress
When a value is written to timer A register, it is written to only reload register (transferred to
counter at next reload timer).
