• Bits 3..0 – PUDx: Port-Wise Pull-up Disable
When these bits are written to one, the port-wise pull-ups in the defined I/O ports are disabled
even if the DDxn and PORTxn Registers are configured to enable the pull-ups ({DDxn, PORTxn}
= 0b01). The Port-Wise Pull-up Disable bits are ORed with the global Pull-up Disable bit (PUD)
from the MCUCR register. See
feature.
