Description
Stop Condition Interrupt Source Mask
Enables or disables the interrupt generation when the
stop condition is detected in slave mode.
0: Enables IRIC flag setting and interrupt generation
1: Disables IRIC flag setting and interrupt generation
for the selection of reception with handshaking.
0: Disables handshake control
1: Enables handshake control
Note: When the IIC module is in use, be sure to set this
When the HNDS bit is cleared to 0 and a round of
reception is completed with ICDRR empty (the ICDRF
flag is 0), successive reception will proceed with the
next round of reception. At the same time, a clock is
continuously supplied over the SCL line.
In this case, the sequence of operations should be
such that unnecessary clock cycles are not output to
the bus after reception of the last of the data.
When the HNDS bit is set to 1, SCL is fixed low and
clock output stops on completion of reception. SCL is
released and reception of the next frame is enabled by
reading the receive data from ICDR.
Enables or disables handshake control in receive mode
when the stop condition is detected (STOP = 1 or
ESTP = 1) in slave mode.
