ICS94228
General I2C serial interface information for the ICS94228
How to Write:
⢠Controller (host) sends a start bit.
⢠Controller (host) sends the write address D2 (H)
⢠ICS clock will acknowledge
⢠Controller (host) sends a dummy command code
⢠ICS clock will acknowledge
⢠Controller (host) sends a dummy byte count
⢠ICS clock will acknowledge
⢠Controller (host) starts sending Byte 0 through Byte 16
(see Note 2)
⢠ICS clock will acknowledge each byte one at a time
⢠Controller (host) sends a Stop bit
How to Read:
⢠Controller (host) will send start bit.
⢠Controller (host) sends the read address D3 (H)
⢠ICS clock will acknowledge
⢠ICS clock will send the byte count
⢠Controller (host) acknowledges
⢠ICS clock sends Byte 0 through byte 6 (default)
⢠ICS clock sends Byte 0 through byte X (if X(H) was
written to byte 6).
⢠Controller (host) will need to acknowledge each byte
⢠Controller (host) will send a stop bit
