TAILOR PIXELS TECHNOLOGY CO., LTD. System reset can be initialized by setting RSTB terminal at low level when turning power on, receiving instruction from MPU. When RSTB becomes low, following procedure is occurred. - Display off - Display start line register become set by 0.(Z-address 0) While RSTB is low level, no instruction except status read can be accepted. Reset status appears at DB4. After DB4 is low, any instruction can be accepted. The Conditions of power supply at initial power up are shown in table 1. Page 14 of 3
