Description
FSI Transmit End Interrupt Flag
[Setting condition]
•
[Clearing condition]
•
Reserved
The read value is undefined, and this bit cannot be
modified.
FSI Receive End Interrupt Flag
Indicates whether or not there is data to be read by
the FSI.
0: There is no read data.
[Clearing condition]
•
1: There is read data.
[Setting condition]
•
Reserved
The initial value should not be modified.
