7540 Group
SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
The 7540 Group is the 8-bit microcomputer based on the 740 family
core technology.
The 7540 Group has a serial I/O, 8-bit timers, a 16-bit timer, and an
A-D converter, and is useful for control of home electric appliances
and office automation equipment.

Note: Serial I/O2 can be used in the following cases;
(1) Serial I/O1 is not used,
(2) Serial I/O1 is used as UART and BRG output divided by 16 is
selected as the synchronized clock.
