32-bit ARM Cortex-M0+ microcontroller

8. Movable functions

Movable functions for the I2C, USART, SPI, CTimer pins 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_17 through

switch matrix)
