Reserved
CLEARPC
Set to clear pending commands.
CLEARTX
Set to clear transmit buffer and shift register. Will not abort ongoing transfer.
ABORT
Abort the current transmission making the bus go idle. When used in combination with STOP, a STOP condition is sent as soon as
possible before aborting the transmission. The stop condition is subject to clock synchronization.
CONT
Set to continue transmission after a NACK has been received.
NACK
Set to transmit a NACK the next time an acknowledge is required.
ACK
Set to transmit an ACK the next time an acknowledge is required.
STOP
Set to send stop condition as soon as possible.
START
Set to send start condition as soon as possible. If a transmission is ongoing and not owned, the start condition will be sent as soon
as the bus is idle. If the current transmission is owned by this module, a repeated start condition will be sent. Use in combination with
a STOP command to automatically send a STOP, then a START when the bus becomes idle.

Description
Software must give one ACK command for each ACK transmitted on the I
Addresses that are not automatically NACK'ed, and all data is automatically acknowledged.
Description
All addresses will be responded to with a NACK
Addresses matching the programmed slave address or the general call address (if enabled) require a response from
software. Other addresses are automatically responded to with a NACK.
