6.2.1 Control register denition
6.3 Register descriptions
6.3.1 INPUT0 - Input register 0
The INPUT0 register reects the state of the device pins (inputs 0 to 7). Writes to this
register will be acknowledged but will have no effect.
Remark: The default value ‘X’ is determined by the externally applied logic level (normally
logic 1) when used for directly driving LED with pull-up to VDD.
6.3.2 INPUT1 - Input register 1
The INPUT1 register reects the state of the device pins (inputs 8 to 15). Writes to this
register will be acknowledged but will have no effect.
Remark: The default value ‘X’ is determined by the externally applied logic level (normally
logic 1) when used for directly driving LED with pull-up to VDD.
