Pinout

Pin	Name	Type	Function
1	PB6	bidirectional	GPIO port B bit 6 (TTL); alternate functions include I2C5SCL (has an active pull-up, so the pin should not be set open-drain), M0PWM0, SSI2Rx and T0CCP0.
2	VDDA	power_in	Positive supply for the analog circuits (ADC, analog comparators); it must be supplied within the Table 23-5 specification regardless of system implementation.
3	GNDA	power_in	Ground reference for the analog circuits (ADC, analog comparators), separated from GND to limit digital noise on the analog functions.
4	PB7	bidirectional	GPIO port B bit 7 (TTL); alternate functions include I2C5SDA (open-drain), M0PWM1, SSI2Tx and T0CCP1.
5	PF4	bidirectional	GPIO port F bit 4 (TTL); alternate functions include QEI0 index IDX0, M0FAULT2, M1FAULT0, T2CCP0 and USB0EPEN (host-mode VBUS power-enable output).
