W90N740CD WINBOND [Winbond], W90N740CD Datasheet - Page 173

• Manufacturer Part Number: W90N740CD
• Description: 32-Bit ARM7TDMI-Based Micro-Controller
• Manufacturer: WINBOND [Winbond]

GPIOCFG11_10 [5:4]: Operating mode for GPIO11 and GPIO10
RxD and TxD are used for the UART console.
GPIOCFG9_4 [3:2]: Operating mode for GPIO9, GPIO8, GPIO7, GPIO6, GPIO5, and GPIO4
nTOE, FSE0, VO, VM, VP, and RCV are the USB IO signal pins, which connected to the external
USB transceiver to control the data in/out.
nDSR, nDTR, nCD, nCTS, nRTS and nRI are the UART modem signal pins.
GPIOCFG3_0 [1:0]: Operating mode for GPIO3, GPIO2, GPIO1, and GPIO0
