Description

ack_bit

This parameter determines which "acknowledge" bit to send to the target I²C peripheral after reading 8 bits of data (enum i2c_ack_nack):

• 0 — ACK
• 1 — NACK

What the target does with this acknowledge bit is device-dependent. Please refer to the datasheet of your attached I²C peripheral for specific details.
