2C-bus Read from Status Register:
I
2C-bus Read Command from the Status Register follows the format shown below. After the START condition, a
slave address is sent by the master. This address is seven bits long followed by an eighth bit which is an opcode
bit (R/
W) – a ‘one’ indicates the master will read data from the status register. After the R/W bit, the ’zero’ ACK bit
is sent to the master by the device. The device now starts sending the 8-bit status register data to the control
register during the DATA bits. After the DATA bits, the ‘one’ ACK bit is sent to the device by the master. The
master should send the STOP condition after receiving the ACK bit.
