The Busy Flag

When the busy flag is “1” it indicates that the ST7565S is

running internal processes, and at this time no command

aside from a status read will be received. The busy flag is

outputted to D7 pin with the read instruction. If the cycle time

(tCYC) is maintained, it is not necessary to check for this flag

before each command. This makes vast improvements in

MPU processing capabilities possible.
