(9) Timer/counter function
This unit incorporates a 2-channel 16-bit timer (TM0) for 3-phase sine wave PWM inverter control, a 2-
channel 16-bit up/down counter (TM1) that can be used for 2-phase encoder input or as a general-purpose
timer, a 2-channel 16-bit general-purpose timer unit (TM2), a 1-channel 16-bit timer/event counter (TM3), and
a 1-channel 16-bit interval timer (TM4) on-chip, and can measure the pulse interval or frequency and can
output a programmable pulse.
(10) Serial interface
A 3-channel asynchronous serial interface (UART), 2-channel clocked serial interface (CSI), and 1-channel
FCAN are provided as serial interfaces.
The UART performs data transfer using pins TXDn and RXDn (n = 0 to 2).
The CSI performs data transfer using pins SOm, SIm, and SCKm (m = 0, 1).
FCAN performs data transfer using pins CTXD and CRXD.
(11) NBD function
There is a 1-channel NBD on-chip as a debugging interface (
(12) A/D converter (ADC)
Two units of a high-speed, high-resolution 10-bit A/D converter having eight analog input pins are
implemented. The ADC converts using a successive approximation method.
