MCU Control Register – MCUCR
Alternate Functions of Port B
• 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} = 0b01). Se
The Port B pins with alternate functions are shown in
Table 9-3.
The alternate pin configuration is as follows:
• ADC4/PSCOUT0B/SCK/PCINT7 – Bit 7
PSCOUT0B, Output 0B of PSC.
