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.
