Description
Receive Data Read Request Flag
Indicates the ICDR (ICDRR) status in receive mode.
[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).
