CONNECTION TO A MICROCOMPUTER
(1) Three-wire serial I/O
(2) Two-wire serial I/O
Notes 1. When only the
µPD72042B is to be controlled from a microcomputer via a serial I/O interface, the CS
pin must be tied low (by connecting it to GND).
2. When an interrupt is detected by polling (in FLG register read), IRQ may be left open. When high-volume
or high-speed data transfer is required, however, the system described above is recommended to ensure
reliable data transfer.
3. Required when the microcomputer’s N-ch open-drain output is used. The SIO pin of the
µPD72042B
is a CMOS I/O pin.
