With the NXP Pins Tool (see “Tutorial: Muxing with the New NXP Pins Tool“) I can configure and mux (multiplex) the microcontroller pins. What is really powerful and what might not be so obvious at the first sight is that it gives me deep control over every register bit and setting. For example I have below the PTB1 (Port B, pin 1) muxed as GPIO (General Purpose I/O):
PTB1 Muxed with Pins Tool
But it only generates this:
void BOARD_InitPins(void) {
CLOCK_EnableClock(kCLOCK_PortB); /* Port B Clock Gate Control: Clock enabled */
PORT_SetPinMux(PORTB, PIN1_IDX, kPORT_MuxAsGpio); /* PORTB1 (pin 54) is configured as PTB1 */
}
So what about all the other bits and pieces? Continue reading
