Bit 7

MLS

Description

MSB-first

(Initial value)

LSB-first

Bit 6—Wait Insertion Bit (WAIT): Selects whether to insert a wait between the transfer of data

and the acknowledge bit, in master mode with the I

2C bus format. When WAIT is set to 1, after the

fall of the clock for the final data bit, the IRIC flag is set to 1 in ICCR, and a wait state begins

(with SCL at the low level). When the IRIC flag is cleared to 0 in ICCR, the wait ends and the

acknowledge bit is transferred. If WAIT is cleared to 0, data and acknowledge bits are transferred

consecutively with no wait inserted.

The IRIC flag in ICCR is set to 1 on completion of the acknowledge bit transfer, regardless of the

WAIT setting.

The setting of this bit is invalid in slave mode.

Bit 6
