6.2.1 Control Register denition
6.3 Register descriptions
6.3.1 INPUT0 - Input register 0
The Input register 0 reects the state of the device pins (inputs LED0 to LED7). 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 Input register 1 reects the state of the device pins (inputs LED8 to LED15). 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.
