Blink Register (LR6)

Initial value

LR6 is an 8-bit write-only register that specifies blink areas. An area is made to blink by writing 1

to the corresponding bit in this register. There are no restrictions on areas that can blink

simultaneously, and the entire screen can be made to blink by writing 1 to all the bits. The setting

in this register is valid only when the BLK bit in LR1 is set to 1.

The blink areas corresponding to the register bits depend on the value of the SOB bit in LR0, as

shown below.

Upon reset, LR6 is initialized to H'00.

Initial value

LR8 is an 8-bit write-only register that specifies the start line of an area made to blink.

Upon reset, LR8 is initialized to H'00.

Bits 7 to 5—Reserved Bits: Bits 7 to 5 are reserved; they should always be cleared to 0.

Bits 4 to 0—Blink Start Line Setting (BSL4 to BSL0): Bits 4 to 0 specify the start line of an

area made to blink. Set a value of [blink start line – 1].
