1.10.1.1 GPIO instantiation information
The device includes a number of pins, PTB0, PTB1, and PTD6, PTD7 with high current
drive capability. These pins can be used to drive LED or power MOSFET directly. The
high drive capability applies to all functions which are multiplexed on these pins (UART,
TPM, SPI, I2C, CLK_OUT...etc)
