Section 15 I
(Only for the H8S/2638, H8S/2639, and H8S/2630)
Bit 0—Acknowledge Bit (ACKB): Stores acknowledge data. In transmit mode, after the
receiving device receives data, it returns acknowledge data, and this data is loaded into ACKB. In
receive mode, after data has been received, the acknowledge data set in this bit is sent to the
transmitting device.
When this bit is read, in transmission (when TRS = 1), the value loaded from the bus line
(returned by the receiving device) is read. In reception (when TRS = 0), the value set by internal
software is read.
In addition, when this bit is written to in reception the transmission acknowledge data setting is
overwritten regardless of the value of TRS. The value loaded from the reception device is
maintained unchanged, so caution is necessary when using bit operation instructions to overwrite
this register.

Description
Receive mode: 0 is output at acknowledge output timing
Transmit mode: Indicates that the receiving device has acknowledged the data (signal
is 0)
Receive mode: 1 is output at acknowledge output timing
Transmit mode: Indicates that the receiving device has not acknowledged the data
(signal is 1)
