Timer
Timebase timer/watchdog timer: 1 channel
8/16-bit PPG timer: 8-bit
× 2 channels or 16-bit × 1 channel
8/16-bit up/down counter/timer: 1 channel (8-bit
× 2 channels)
16-bit I/O timer
16-bit free run timer: 1 channel
Input capture (ICU): Generates an interrupt request by latching a 16-bit free run timer counter value upon
detection of an edge input to the pin.
Output compare (OCU): Generates an interrupt request and reverse the output level upon detection of a match
between the 16-bit free run timer counter value and the compare setting value.
Extended I/O serial interface: 3 channels
I2C interface (1 channel)
Serial I/O port for supporting Inter IC BUS
UART0 (SCI), UART1 (SCI)
With full-duplex double buffer
Clock asynchronized or clock synchronized transmission can be selectively used.
DTP/external interrupt circuit (8 channels)
A module for starting extended intelligent I/O service (EI2OS) and generating an external interrupt triggered
by an external input.
Delayed interrupt generation module
Generates an interrupt request for switching tasks.
