12.6.14 DPDS1 – Port Driver Strength Register 1
8266A-MCU Wireless-12/09
The output driver strength can be set individually for each digital I/O port. The following
table shows output current levels for a typical supply voltage of DEVDD = 3.3V. Refer to
section "Electrical Characteristics" for details.
• Bit 7:2 – Res5:0 - Reserved
• Bit 1:0 – PGDRV1:0 - Driver Strength Port G
Driver strength can be set for port G except the port pins PG3 and PG4. The leakage
current of the ports PG3 and PG4 is reduced.
