In receive mode, data is latched at the rise of the transfer clock. The transfer clock is output when
MST in ICCR1 is 1, and is input when MST is 0. For receive mode operation timing, refer to
figure 17.15. The reception procedure and operations in receive mode are described below.
1. Set the ICE bit in ICCR1 to 1. Set bits CKS[3:0] in ICCR1. (Initial setting)
2. When the transfer clock is output, set MST to 1 to start outputting the receive clock.
3. When the receive operation is completed, data is transferred from ICDRS to ICDRR and
4. To stop receiving when MST = 1, set RCVD in ICCR1 to 1, then read ICDRR. Then, SCL is
Notes: Follow the steps below to receive only one byte with MST = 1 specified. See figure 17.16

RDRF in ICSR is set. When MST = 1, the next byte can be received, so the clock is
continually output. The continuous reception is performed by reading ICDRR every time
RDRF is set. When the 8th clock is risen while RDRF is 1, the overrun is detected and
AL/OVE in ICSR is set. At this time, the previous reception data is retained in ICDRR.
fixed high after receiving the next byte data.
Receive Operation
1. Set the ICE bit in ICCR1 to 1. Set bits CKS[3:0] in ICCR1. (Initial setting)
2. Set MST = 1 while the RCVD bit in ICCR1 is 0. This causes the receive clock to be
3. Check if the BC2 bit in ICMR is set to 1 and then set the RCVD bit in ICCR1 to 1.
for the operation timing.
output.
This causes the SCL to be fixed to the high level after outputting one byte of the
receive clock.
