40-bit Fm+ I2C-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
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.
