(4) Microcontroller Registers
[a] Read/Write
Addresses 0040h to 0046h, 0048h, and 004Ah are read-only registers.
Data can be written to and read from addresses with register marks if they are not read-only registers.
Although data can be written to addresses with no register marks, the accuracy of data read from such
addresses is not guaranteed.
[b] Special Registers
Addresses 0043h and 0044h are registers, the functions of which vary with the signal mode settings for
the registers.
• NTSC mode: Register for VBID detection
• PAL mode: Register for WSS detection (The register table in WSS mode is different.)
[c] Video Signal Mode Settings
A video signal mode is set with three bits. These bits have the following meanings.
