FUNCTION
The M54610P, when used in a printer, is capable of implementing
a standard 8-bit parallel data interface. As shown in the timing
diagram, printing data DIN 1 through 8 and strobe pulses STB are
input from a host computer. Data are exchanged by outputing the
BUSY and ACK (ACKNOWLEDGE) signals to the host computer.
Control signals EBSY, CS, WR, RD and ACKI are input from a
printer controller, and this IC outputs DOU 1 through 8, and BSYF.
