MCU Control Register – MCUCR
Port Control Register – PORTCR
• Bit 4 – PUD: Pull-up Disable
When this bit is written to one, the pull-ups in the I/O ports are disabled even if the DDxn and
PORTxn Registers are configured to enable the pull-ups ({DDxn, PORTxn} = 0, 1). See
figuring the Pin” on page 91
• Bits 5, 4 – BBMx: Break-Before-Make Mode Enable
When these bits are written to one, the port-wise Break-Before-Make mode is activated. The
intermediate tri-state cycle is then inserted when writing DDRxn to make an output. For further
information, see
• Bits 1, 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} = 0, 1). The Port-Wise Pull-up Disable bits are ORed with the global Pull-up
Disable bit (PUD) from the MCUCR register. See
details about this feature.
