Description
The next transmit data is in ICDR (ICDRT), or transmission cannot
be started
[Clearing conditions]
The next transmit data can be written in ICDR (ICDRT)
[Setting conditions]
Description
The data in ICDR (ICDRR) is invalid
[Clearing condition]
When ICDR (ICDRR) receive data is read in receive mode
The ICDR (ICDRR) receive data can be read
[Setting condition]
When data is transferred from ICDRS to ICDRR
(Data transfer from ICDRS to ICDRR in case of normal termination with TRS = 0 and
RDRF = 0)
2
C Bus Interface [Option]
When transmit data is written in ICDR (ICDRT) in transmit mode (TRS = 1)
When a stop condition is detected in the bus line state after a stop condition is
issued with the I
When a stop condition is detected with the I
In receive mode (TRS = 0)
(A 0 write to TRS during transfer is valid after reception of a frame containing an
acknowledge bit)
In transmit mode (TRS = 1), when a start condition is detected in the bus line state
after a start condition is issued in master mode with the I
format selected
At the first transmit mode setting (TRS = 1) (first transmit mode setting only) after
the mode is switched from I
When data is transferred from ICDRT to ICDRS
(Data transfer from ICDRT to ICDRS when TRS = 1 and TDRE = 0, and ICDRS is
empty)
When detecting a start condition and then switching from slave receive mode (TRS
= 0) state to transmit mode (TRS = 1) (first transmit mode switching only).
