CYAT81688如何切换模式

状态机

在这里插入图片描述

Mode Change Timing Diagram

在这里插入图片描述

举例

现在CYAT81688芯片处于 System information，我想切换到Operation Mode
如何做？（7-bit I2C slave address of 0x24）((using synchronous level
handshaking)

(wait for communications interrupt)
w 24 00
r 24 x x x x x x x x ; read 8 bytes
w 24 00 90 ; sys info mode and toggle bit
(wait for communications interrupt)
r 24 x x x x x x x x ; read 8 bytes
w 24 00 10 ; sys info mode and toggle bit
(wait for communications interrupt)
w 24 00 88 ; operating mode and toggle bit
(before writing again, wait at least T(refresh); for new data, wait for the communications interrupt)
