All Digital IO include configurable drive strength namely low-drive (12 mA) and high-
drive (16 mA) modes. By default, all digital IOs come up in low-drive mode.
All Digital IO include a configurable pullup with pull-up disabled by default, except for
F_20, F_22, F_23 (TRST_N, TMS, TDI)) where pull-up is enabled by default.
UART_A/B_CTS (input) or UART_A/B_RE (output) is available based on UART mode of
operation (RS232 or RS485) configurable in respective UART controller. Similarly for
UART_A/B_RTS (output) or UART_A/B_DE (output). Default is RS232. FW can choose
to enable both input and output direction for CTS/RE pins and hardware will control
the output enable of these pins based on RS232 or RS485 mode of operation if these
pins are configured for UART function.
JTAG interface is default enabled (user mode 0) to assist in debug as well as
embedded flash programming.
There is a F_25 pad which is not bonded to any pin. This pad (mapped as pin 25 for
pinmux configuration in System Control Subsystem) shall be configured by FW in
input disabled mode (Input Enable = 0; User mode 3 which makes Output Enable
disabled).
DVDD_2 and DVDD are identical and are to be connected to the same source.
