1. DESCRIPTION
The M37160M8/MA/MF-XXXSP/FP and M37160EFSP/FP are single-
chip microcomputers designed with CMOS silicon gate technology.
They have an OSD and I2C-BUS interface, making them perfect for
a channel selection system for TV.
The M37160EFSP/FP has a built-in PROM that can be written elec-
trically.

FSCIN Pin
The FSCIN pin is a reference clock input pin. The main clock and
OSD clock are generated based on the reference clock from the
FSCIN pin. The sub clock can also be generated directly from the 32
kHz oscillator circuit and FSCIN pin. Refer to the clock generating
circuit shown in Figure 8.13 Clock Generating Circuit.
