14.4 Register Description
14.4.1 MCUCR – MCU Control Register
14.4.2 DPDS0 – Port Driver Strength Register 0
8266B-MCU Wireless-03/11
The MCU Control Register contains control bits of the general Microcontroller Unit
functions.
• Bit 4 – PUD - Pull-up Disable
When this bit is written to one, the I/O ports pull-up resistors are disabled even if the
DDxn and PORTxn Registers are configured to enable the pull-up resistor ({DDxn,
PORTxn} = 2'b01). See section "Ports as General Digital I/O" for more details about this
feature.
The output driver strength can be set individually for each digital I/O port. The following
tables show output current levels for a typical supply voltage of DEVDD = 3.3V. Refer to
section "Electrical Characteristics" for details.
• Bit 7:6 – PFDRV1:0 - Driver Strength Port F

• Bit 5:4 – PEDRV1:0 - Driver Strength Port E
