1.1 Performance overview
The 8-bit microcomputers:
-M37221M4-XXXSP
-M37221M6-XXXSP/FP
-M37221M8-XXXSP
-M37221MA-XXXSP
-M37220M3-XXXSP/FP
have their simple instruction set; the ROM, RAM, and I/O addresses are placed on the same memory map
to enable easy programming.
Furthermore, they have many additional functions for tuning system for TV:
PWM output (14-bit and 8-bit)
CRT display
A-D comparator (resistance string method)
Software runaway detection
Multi-master I
2
C-BUS interface function
ROM correction function
And also, they can allow low power dissipation by the use of CMOS processing.
The M37221M6-XXXSP/FP is used as a general example in describing the functions of the above microcomputers,
unless otherwise noted.
