Command/Data
Flag
When the host writes to IDR3, bit 2 of the I/O
address is written into this bit to indicate whether
IDR3 contains data or a command.
0: Content of input data register (IDR3) is a data
1: Content of input data register (IDR3) is a
command

R
R
Input Data Register Full
Indicates whether or not there is receive data in
IDR3. This is an internal interrupt source to the
slave (this LSI).
0: There is not receive data in IDR3
[Clearing condition]
When the slave reads IDR3
1: There is receive data in IDR3
[Setting condition]
When the host writes to IDR3 in an I/O write cycle
0 OBF3A
0
R/(W)
*
R
Output Data Register Full
Indicates whether or not there is transmit data in
ODR3.
0: There is not transmit data in ODR3
[Clearing conditions]
•
When the host reads ODR3 in an I/O read cycle
•
When the slave writes 0 to bit OBF3A
1: There is transmit data in ODR3
[Setting condition]
•
When the slave writes to ODR3
Note:
*
Only 0 can be written to clear the flag.
