A/D converter
10-bit resolution, 5.2
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.

free-run timer. 1 channel
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.
