  • Built - in FIFO for conversion data storage (for SCAN conversion: 16 steps, for Priority conversion: 4 steps)
• Base Timer (Max 8 channels)
  • Operation mode is selectable from the followings for each channel:
    • 16 - bit PWM timer
    • 16 - bit PPG timer
    • 16 - /32 - bit reload timer
    • 16 - /32 - bit PWC timer
• 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
• 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)
  • Year/Month/Day/Hour/Minute/Second/A day of the week from 00 to 99.
  • The interrupt function with specifying date and time (Year/Month/Day/Hour/Minute) 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.
