Description
Receive Data Read Request Flag
Indicates the ICDR (ICDRR) status in receive mode.
0: Indicates that the data has been already read from
1: Indicates that data has been received successfully and
[Setting conditions]
•
[Clearing conditions]
•
•
When ICDRF is set due to the condition (2) above, ICDRF
is temporarily cleared to 0 when ICDR (ICDRR) is read;
however, since data is transferred from ICDRS to ICDRR
immediately, ICDRF is set to 1 again.
Note that ICDR cannot be read successfully in transmit
mode (TRS = 1) because data is not transferred from
ICDRS to ICDRR. Be sure to read data from ICDR in
receive mode (TRS = 0).
(1) When data is received successfully while ICDRF = 0
(2) When ICDR is read successfully in receive mode after
ICDR (ICDRR) or ICDR is initialized.
transferred from ICDRS to ICDRR, and the data is ready
to be read out.
