9.1.12 Set Bit
REGISTER
Instruction Register
Bit Set Register
The Clear/Set bit instruction sets 1 bit in a byte of display data RAM to 0 or 1, respectively. The position of the bit in a byte is
specified by NB and RAM address is specified by cursor address. After the ex ecution of the instruction, the cursor address is
automatically increased by 1. NB is a value of 1 to 8.
9.1.13 Read Busy Flag
REGISTER
Busy Flag
When the read mode is set with RS=1, the busy flag is output to DB7. The busy flag is set to 1 during the ex ecution of any of
instructions (1) to (13). After the ex ecution, it is set to 0. The nex t instruction can be accepted. No instruction can be accepted
when busy flag=1. Before ex ecuting an instruction or writing data, perform a busy flag check to make sure that busy flag is 0.
When data is written in the register (RS=1), no busy flag changes. Thus, no busy flag check is required just after the write
operation into the instruction register with RS=1. The busy flag can be read without specifying any instruction register.
