NACKF
When data is transferred from ICDRT to ICDRS
and ICDRT becomes empty
When the TRS bits are set
When the start (re-transmit included) condition has
been issued
When switched from reception to transmission in
slave mode
When 0 is written to this bit after reading TDRE = 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 written to ICDRT
When the ninth clock of SCL rises while the TDRE
flag is 1
When 0 is written to this bit after reading TEND = 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 written to ICDRT
