 General-Purpose I/O Port

This series can use its pins as general-purpose I/O ports when they are not used for external bus or

peripherals. Moreover, the port relocate function is built in. It can set which I/O port the peripheral function

can be allocated to.

 Capable of pull-up control per pin

 Capable of reading pin level directly

 Built-in the port relocate function

 Up to 83 fast general-purpose I/O Ports@100 pin Package

 Some ports are 5V tolerant I/O.

See Pin Description to confirm the corresponding pins.

 Dual Timer (32-/16-bit Down Counter)

The Dual Timer consists of two programmable 32-/16-bit down counters.

Operation mode is selectable from the followings for each channel.

 Free-running

 Periodic (=Reload)

 One-shot

 HDMI-CEC/Remote Control Receiver (Up to 2 channels)

 HDMI-CEC transmitter

 Header block automatic transmission by judging Signal free

 Generating status interrupt by detecting Arbitration lost

 Generating START, EOM, ACK automatically to output CEC transmission by setting 1 byte data

 Generating transmission status interrupt when transmitting 1 block (1 byte data and EOM/ACK)

 HDMI-CEC receiver

 Automatic ACK reply function available

 Line error detection function available

 Remote control receiver

 4 bytes reception buffer

 Repeat code detection function available

 Real-time clock (RTC)

The Real-time clock can count Year/Month/Day/Hour/Minute/Second/A day of the week from 01 to 99.

 The interrupt function with specifying date and time (Year/Month/Day/Hour/Minute/Second/A day of

the week.) is available. This function is also available by specifying only Year, Month, Day, Hour or

Minute.

 Timer interrupt function after set time or each set time.

 Capable of rewriting the time with continuing the time count.

 Leap year automatic count is available.

 Watch Counter

The Watch counter is used for wake up from sleep and timer mode.

Interval timer: up to 64 s (Max) @ Sub Clock : 32.768 kHz
