DESCRIPTIONS
The FUJITSU MB90420G/425G Series is a 16-bit general purpose high-capacity microcontroller designed for
vehicle meter control applications etc.
The instruction set retains the same AT architecture as the FUJITSU original F
2
MC-8L and F
2
MC-16L series, with
further refinements including high-level language instructions, expanded addressing mode, enhanced (signed)
multipler-divider computation and bit processing.
In addition, a 32-bit accumulator is built in to enable long word processing.

FEATURES
• 16-bit input capture (4 channels)
Detects rising, falling, or both edges.
16-bit capture register
×
4
Pin input edge detection latches the 16-bit free-run timer counter value, and generates an interrupt request.
• 16-bit reload timer (2 channels)
16-bit reload timer operation (select toggle output or one-shot output)
Event count function selection provided
