25 / 71 page ![]() ST7565P Ver 2.1b 25/71 2009/09/14 The Busy Flag When the busy flag is “1” it indicates that the ST7565P 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.
