32-bit Arm Cortex-M0+ microcontroller

8. Movable functions

Movable functions for the I2C, USART, SPI, CTimer pins, Capacitive Touch, and other

peripherals can be assigned through the switch matrix to any pin that is not power or

ground in place of the fixed functions of the pin.

Table 5.

Movable functions (assign to pins PIO0_0 to PIO0_5, PIO0_7 to PIO0_30 through

switch matrix)
