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.
When data is received successfully and transferred
from ICDRS to ICDRR.
