 Conditions to cause this failure
Low-fixation of the SCL pins is cancelled incorrectly when the following conditions are
satisfied.
Master mode:
Figure 15.19 shows the notes on ICDR reading (TRS = 1) in master mode.
(a) When previously received 2-byte data remains in ICDR unread (ICDRS are full).
(b) Reads ICDR register after switching to transmit mode (TRS = 1). (RDRF = 0 state)
(c) Sets to receive mode (TRS = 0), after transmitting the first frame of issued start
Slave mode:
Figure 15.20 shows the notes on ICDR writing (TRS = 0) in slave mode.
(a) Writes ICDR register in receive mode (TRS = 0), after entering the start condition by
(b) Address match with the first frame, receive 1 by R/W bit, and switches to transmit
When these conditions are satisfied, the low fixation of the SCL pins is cancelled without
ICDR register access after the first frame is transferred.
