Product specification
Microcontrollers for NTSC TVs with On-Screen
Display (OSD) and Closed Caption (CC)
P8xCx70 family
18.6
Memory mapping
All registers and RAM in the display section are mapped into the upper 32-kbyte external RAM range of the 80C51 core.
When writing to the display section, memory units (CLUT and the Display RAM) have wider formats than 8-bits.
Two bytes are written for each word, the first byte (even addresses), addresses the lower 8-bits; the lower nibble of the
second byte (odd addresses), addresses the upper 4-bits.
18.6.1

CCESSING MEMORY
The memories can be accessed by the microprocessor as if it is external RAM.
