2.3.1 Overview

The F280049C MCU is a very versatile device in a small package. To balance compatibility with BoosterPack standards as well as showcasing the versatility of the F280049C, some complexity was added to the design. Most features aligning with the BoosterPack standard are available by default. The additional functions are selected using a switches, or static resistors which can be added or removed. This section covers the alternate functions and how to enable them. Note that by enabling certain alternate features, standard BoosterPack functionality may be lost. The switches are configured such that it is not possible to connect multiple functions to the same header.

Table 4 is a master list of all of the possible functions controlled by the alternate routing switches:

Table 4. Alternate Function Switch Settings

Pins	S3.1	S3.2	S4	S6	S8	S9	Function	Note
GPIO28/GPIO29	x	x	x	0	0	x	SCIA to virtual COM port	Default configuration
GPIO28/GPIO29	x	x	x	1	x	x	SCIA to BoosterPack Site 2
GPIO35/GPIO37	1	x	1	x	1	x	SCIA to virtual COM port
	1	x	0	x	x	x	I2C on BoosterPack Site 1	Default configuration
	0	x	1	x	x	x	QEP1 on J12
GPIO59	0	x	x	x	x	x	QEP1 on J12
GPIO59	1	x	x	x	x	x	GPIO on BoosterPack Site 1	Default configuration
GPIO14/GPIO15/GPIO26	x	0	x	x	x	x	QEP2 on J13
GPIO14/GPIO15/GPIO26	x	1	x	x	x	x	GPIO on BoosterPack Site 2	Default configuration
GPIO32/GPIO33 ⁽²⁾	x	x	x	x	x	0	CAN on J14
GPIO32/GPIO33 ⁽²⁾	x	x	x	x	x	1	GPIO on BoosterPack Site 2	Default configuration

Cells marked with 'x' indicate that the state of that switch has no impact on the function of that particular signal.
GPIO33 is also connected to the FSIRXCLK pin on J11 through a 0 Ω resistor R46. If CAN functionality is required, ensure that R46 is populated.
