Multi-Function
Timer
14-bit up/down count timer × 1, buffered compare register × 4, buffered compare clear
register, zero detect terminal control, 4 output channels, non-overlapped 3-phase waveform
output, 3-phase independent dead time timer, 4-bit carrier counter
UART
Full duplex double buffer
Selectable clock synchronous/asynchronous operation
Built-in dedicated baud rate generator (During asynchronous operation: 62500, 31250,
19230, 9615, 4808, 2404, 1202 bps)
A/D Converter

A/D conversion time
Startup trigger
Activiation
: 6.13 µs (98 machine cycles at 16 MHz machine clock,
includes sample hold time)
: Startup by software, external source, or multi-function
timer output (RT0) can be selected
: Single, scan (multiple channel continuous), continuous
(1 channel continuous), stop (synchronized with
conversion start in scan mode)
16-Bit Reload
Timer
16-bit reload timer operation (toggle output, one-shot output selectable)
(Count clock can be selected from 0.125 µs, 0.5 µs, or 2.0 µs at 16 MHz machine cycle)
Event count function selectable
4 channels built-in
8-Bit PWM
8-bit resolution PWM operation (arbitrary cycle: duty ratio pulse output)
(Count clock can be selected from 0.125 µs or 64.0 µs at 16 MHz machine cycle)
External Interrupts Number of inputs: 8
External interrupt mode (Interrupts can be generated by four types of request detect
sources)
PLL Function
1/2/3/4-time multiplier can be selected (Please set so as not to exceed guaranteed
operation frequency)
