40-bit Fm+ I

C-bus advanced I/O port with RESET, OE and INT

7.3.1 5-bank register category

IP – Input registers

OP – Output registers

PI – Polarity Inversion registers

IOC – I/O Configuration registers

MSK – Mask interrupt registers

If the Auto-Increment flag is set (AI = 1), the 3 least significant bits are automatically 
incremented after a read or write. This allows the user to program and/or read the 
5 register banks sequentially.

If more than 5 bytes of data are written and AI = 1, previous data in the selected registers 
will be overwritten or reread. Reserved registers are skipped and not accessed (refer to 

Table 3

).

If the Auto-Increment flag is cleared (AI = 0), the 3 least significant bits are not 
incremented after data is read or written, only one register will be repeatedly read or 
written.

7.3.2 1-bank register category

OUTCONF – Output Structure Configuration register

ALLBNK – All Bank Control register

MODE – Mode Selection register

If more than 1 byte of data is written or read, previous data in the same register is 
overwritten independently of the value of AI.
