(Continued)
Five timer systems
8-bit PWM timer with 2 channels (usable as either interval timer of PWM timer)
Pulse width count timer (supports continuous measurement or remote control receiving applications)
16-bit timer counter
21-bit time base timer
Watch prescaler (17-bit)
UART
Synchronous or asynchronous operation, switchable
2 serial interfaces (serial I/O)
Selection of transfer direction (specify MSB first or LSB first) for communication with a variety of devices
10-bit A/D converter (8 channels)
External clock input for startup support (except for MB89F538L)
Time base timer output for startup support
Pulse generators (PPG) with 2-program capability
6-bit PPG with selection of pulse width and pulse period
12-bit PPG (2 channels) with selection of pulse width and pulse period
I2C* interface circuits
External interrupt 1 (single-clock : 4 channels, dual-clock : 3 channels)
