11.13.14 PINnCTRL - Pin n Configuration Register
8210B–AVR–04/10
• Bit 7 - Reserved
This bit is reserved and will always be read as zero. For compatibility with future devices, always
write this bit to zero when this register is written.
• Bit 6 - INVEN: Inverted I/O Enable
Setting this bit will enable inverting output and input data on pin n.
• Bit 5:3 - OPC: Output and Pull Configuration
These bits sets the Output/Pull configuration on pin n according to
Table 11-4.
• Bit 2:0 - ISC[2:0]: Input/Sense Configuration
These bits sets the input and sense configuration on pin n according to
configuration decides how the pin can trigger port interrupts and events. When the input buffer is
not disabled, the schmitt triggered input is sampled (synchronized) and can be read in the IN
register.
