*
: This register is set to the all bits zero state when the IC is reset by the RST pin.
When transparent is selected, the BLK output is set to the low level. (Transparent state)
The RGB outputs are values from the color table.
The transparent specification is best for color table 1, address 0000.
Since the data is set to all zeros by a RAM clear operation,
The RGB output will be 000 (black) and the BLK output will be 1.
Transparent is specified by setting the TOK bit to 1. (The BLK output will go to the low level.)
