RC successive approximation, 8 channels (multiplexed inputs)
8-bit resolution
R-2R type, 2 channels (independent)
Full-duplex, double-buffered (8-bit), internal baud rate correction circuit that uses the
operating clock
NRZ-type transfer, supports MIDI frequencies, 2 channels
8-bit data register. LSB-first or MSB-first operation can be selected.
The transfer shift clock can be input externally.
The internal shift clock includes a built-in operating clock correction circuit. 1 channel
Can operate as two independent channels in 8-bit mode.
Can also be used as a single-channel 16-bit PPG. 1 channel
6 event inputs. Can operate as two independent 8-bit up/down counter channels. Can
also be used as a single-channel 16-bit counter. Includes reload and compare functions.

Oscillation
stabilization delay
time
Includes sleep, stop, and hardware standby functions
The initial value of the oscillation stabilization delay time is 64 ms.
The oscillation stabilization delay time can also be set to 0 ms, 2.05 ms, 8.19 ms, or
64 ms (for an crystal oscillator).
The MB90630A series are for FAR oscillators.
8 inputs
External interrupt mode
(Interrupts can be generated from four different types of request signal)
Selectable multiplier: 1/2/3/4
(Set a multiplier that does not exceed the assured operation frequency range.)
