5Peripherals support
Debug UART: GPIOB_[0..1]
JTAG: GPIOE_[0..4]
5.1 Pin function table setup
Multiple functions are supported by group setup.
For example: GPIOA_6(Rx), GPIOA_7(Tx), GPIOA_3(RTS) and
GPIOA_5(CTS) are used if UART0 function. GPIOA_3(RTS) and
GPIOA_5(CTS) can not be used as other functions.
For example: GPIOC_0, GPIOC_1, GPIOC_2, GPIOC_2, GPIOC_3 are
used if PWM is occupied. GPIOC_1(PWM1) and GPIOC_2(PWM2) can
not be used as other functions.
NOTE1: PH = Pull-High, HI = High-impedance
NOTE2: GPIOA_1 needs external Circuit to do the pull high control; others’ pull
control can be done by register setting (including GPIOA_1’s PD).

6Hardware configuration
6.1CMSIS-DAP
RTL-AMEBA_DEV01 supports CMSIS-DAP debugger. It requires installing
“serial to USB driver”at first. Serial to USB driver can be found in
tools\serial_to_usb\mbedWinSerial_16466.
Connect board to the PC with micro-USB cable.

6.2J-Link/JTAG
Weld JTAG and log UART connectors to HDK board and connect with pitch
2.54mm 2x5pins connector. It is recommended to weld the connector on the
bottom side. Users can connect extension boards from top side.
Dupont Line or 2.54mm 2x5 pins connector.
