Output Buffer Full
Set to 1 when the slave processor (this LSI) writes to
ODR. Cleared to 0 when the host processor reads
ODR.
0: [Clearing condition]
When the host processor reads ODR using I/O read
cycle, or the slave processor writes 0 to the OBF bit
1: [Setting condition]
When the slave processor writes to ODR
Defined by User
The user can use these bits as necessary.
Command/Data
When the host processor writes to an IDR register,
bit 2 of the I/O address is written into this bit to
indicate whether IDR contains data or a command.
0: Contents of data register (IDR) are data
1: Contents of data register (IDR) are a command
Defined by User
The user can use this bit as necessary.
