    Register description
    14.3.5
    MCUCR – MCU Control Register
    Note:
    1. Only available in the Atmel ATmega164PA/324PA/644PA/1284P.
    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). See ”Con-
    figuring the Pin” on page 73 for more details about this feature.
