Preliminary
GPIO Interface
All GPIOs are capable of sinking and sourcing 8mA of I/O current. GPIO [0] to GPIO [7] are internally
pulled down with 100KΩ (nominal) resistors GPIO [8] to GPIO [15] are internally pulled up with 100KΩ
(nominal) resistors.
UART Interface
The UART is compatible with the 16550 industry standard. Four signals are provided with the UART
interface. The TXD and RXD pins are used for data while the CTS and RTS pins are used for flow
control.
