Table 1.2-1 Features of the MB90390 Series (2/3)
Features
Rising edge, falling edge or rising & falling edge sensitive
16-bit Input
Six 16-bit Capture registers
Capture
Signals an interrupt upon external event
(6 channels)
ICU3/ICU5 inputs are shared with OCU6/OCU7 outputs

Twelve 8-bit reload counters
Twelve 8-bit reload registers for "L" pulse width
8/16-bit
Twelve 8-bit reload registers for "H" pulse width
Programmable
A pair of 8-bit reload counters can be configured as one 16-bit reload counter or as 8-bit prescaler
Pulse Generator
plus 8-bit reload counter
(6 channels)
Operation clock freq.: fsys/2
(fsys = System clock frequency, fosc = Oscillation clock frequency)
5 channels

Stepper Motor
Four high current outputs with controlled slew rate for each channel
Controller
Synchronized two 8-bit PWM's for each channel
(6 channels)
External Interrupt
Can be programmed edge sensitive or level sensitive
(8 channels)
8-bit PWM signal is mixed with tone frequency from 8-bit reload counter
Sound Generator
PWM frequency: 62.5kHz, 31.2kHz, 15.6kHz, 7.8kHz at System clock = 16MHz
Tone frequency: PWM frequency / 2 / (reload value + 1)

All push-pull outputs
I/O Ports
Bit-wise programmable as input/output or peripheral signal
Port-wise programmable as CMOS Hysteresis or Automotive Hysteresis input (default)
Spread spectrum clock modulator for reducing electromagnetic emissions.
Frequency and Phase Modulation modes.
Clock Modulator
MB90F394H: do not use frequency modulation!
