Instruction Description
Busy Flag/Key Scan Read
The busy flag/key scan read instruction (Figure 5) reads scan data SD3 to SD0 latched into scan registers
SCAN0 to SCAN7, scan cycle state SF1 and SF0, and transfer flag TF, sequentially. It also reads the busy
flag (BF) indicating that the system is now internally operating on a previously received instruction. If BF
is 1, the internal operation is in progress. The next instruction will not be accepted until BF is cleared to 0.
Adjust the data transfer rate so that the last bit of the next instruction is received after BF is cleared to 0.

Clear Display
The clear display instruction (Figure 6) writes space code 20H (character pattern for character code 20H
must be a blank pattern) into all DDRAM addresses. It then sets DDRAM address 0 into the address
counter. It also sets I/D to 1 (increment mode) in the entry mode set instruction.
