When receive data is transferred from ICDRS to
ICDRR
When 0 is written to this bit after reading RDRF = 1
(When the CPU is used to clear this flag by writing
0 while the corresponding interrupt is enabled, be
sure to read the flag after writing 0 to it.)
When data is read from ICDRR
When no acknowledge is detected from the receive
device in transmission while the ACKE bit in ICIER
is set to 1
When 0 is written to this bit after reading NACKF =
1
(When the CPU is used to clear this flag by writing
0 while the corresponding interrupt is enabled, be
sure to read the flag after writing 0 to it.)
When a stop condition is detected after frame
transfer
When 0 is written to this bit after reading STOP = 1
(When the CPU is used to clear this flag by writing
0 while the corresponding interrupt is enabled, be
sure to read the flag after writing 0 to it.)
