M37272M6/M8–XXXSP/FP, M37272MA–XXXSP
M37272E8SP/FP, M37272EFSP
SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER with CLOSED CAPTION DECODER
and ON-SCREEN DISPLAY CONTROLLER
1. DESCRIPTION
The M37272M6/M8-XXXSP/FP and M37272MA-XXXSP are single-
chip microcomputers designed with CMOS silicon gate technology.
They have a OSD, data slicer, and I2C-BUS interface, so it is useful
for a channel selection system for TV with a closed caption decoder.
The features of the M37272E8SP/FP and M37272EFSP are similar
to those of the M37272M6-XXXSP except that the chip has a built-in
PROM which can be written electrically. The difference between
M37272M6-XXXSP/FP, M37272M8-XXXSP/FP and M37272MA-
XXXSP are the ROM size and RAM size. Accordingly, the following
descriptions will be for the M37272M6-XXXSP/FP.

instructions or the SERIES 740 <Software> User’s Manual for de-
tails on the instruction set.
Machine-resident 740 Family instructions are as follows:
The FST, SLW instruction cannot be used.
The MUL, DIV, WIT and STP instructions can be used.
8.1.1 CPU Mode Register
The CPU mode register contains the stack page selection bit and
internal system clock selection bit. The CPU mode register is allo-
cated at address 00FB16.
