M37220M3-XXXSP
SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER for VOLTAGE SYNTHESIZER
with ON-SCREEN DISPLAY CONTROLLER
DESCRIPTION
The M37220M3-XXXSP is a single-chip microcomputer designed with
CMOS silicon gate technology. It is housed in a 42-pin shrink plastic
molded DIP.
In addition to their simple instruction sets, the ROM, RAM and I/O
addresses are placed on the same memory map to enable easy pro-
gramming.
The M37220M3-XXXSP has a PWM output function and a OSD dis-
play function, so it is useful for a channel selection system for TV.

Looking for a programming direction
The question is very simple. Given a variable a, and assigning it an 8-bit value b, you are required to reverse the order of a first (for example, 12345678 becomes 87654321) and then assign it to b. H...
