„Ports
• Input / Output Ports
: 5 ports (28 terminals)
Data direction programmable in nibble units
: 1 port (8 terminals)
(If the N-ch open drain output is selected by option, the corresponding port data can be read in output mode.)
Data direction programmable for each bit individually : 4 ports (20 terminals)
„AD converter
• 4 channels×8-bit AD converters
„Serial interfaces
• IIC-bus compliant serial interface (Multi-master type)
Consists of a single built-in circuit with two I/O channels. The two data lines and two clock lines can be connected
internally.
• Synchronous 8-bit serial interface
„PWM output
• 3 channels×7-bit PWM
„Timer
• Timer 0 : 16-bit timer/counter
With 2-bit prescaler + 8-bit programmable prescaler
Mode 0 : Two 8-bit timers with a programmable prescaler
Mode 1 : 8-bit timer with a programmable prescaler + 8-bit counter
Mode 2 : 16-bit timer with a programmable prescaler
Mode 3 : 16-bit counter
The resolution of timer is 1 tCYC.
• Timer 1 : 16-bit timer/PWM
Mode 0 : Two 8-bit timers
Mode 1 : 8-bit timer + 8-bit PWM
Mode 2 : 16-bit timer
Mode 3 : Variable bit PWM (9 to 16 bits)
In mode0/1, the resolution of Timer1/PWM is 1 tCYC
In mode2/3, the resolution is selectable by program; tCYC or 1/2 tCYC
• Base timer
Generate every 500ms overflow for a clock application (using 32.768kHz crystal oscillation for the base timer clock)
Generate every 976µs, 3.9ms, 15.6ms, 62.5ms overflow (using 32.768kHz crystal oscillation for the base timer clock)
Clock for the base timer is selectable from 32.768kHz crystal oscillation, system clock or programmable prescaler
output of Timer 0
„Remote control receiver circuit (connected to the P73/INT3/T0IN terminal)
• Noise rejection function
• Polarity switching
„Watchdog timer
External RC circuit is required
Interrupt or system reset is activated when the timer overflows
„ROM correction function
