Pin Management
Here is a table I made to make MSP430FR5739 resource management easier.
I find it very useful to work out what resources are available to use.
| Pin Name | FraunchPad Function | Special Function | Selected Function | Assigned Use |
|---|---|---|---|---|
| P1.0 | TA0.1/DMAE0/RTCCLK/A0/CD0/VeREF- | |||
| P1.1 | TA0.2/TA1CLK/CDOUT/A1/CD1/VeREF+ | |||
| P1.2 | TA1.1/TA0CLK/CDOUT/A2/CD2 | |||
| P1.3 | Wi-Fi nCS | TA1.2/UCB0STE/A3/CD3 | ||
| P1.4 | (NTC Thermistor) | TB0.1/UCA0STE/(A4)/CD4 | ||
| P1.5 | TB0.2/UCA0CLK/A5/CD5 | |||
P1.6 | Wi-Fi SPI DOUT | TB1.1/UCB0SIMO/UCB0SDA/TA0.0 | ||
| P1.7 | Wi-FI SPI DIN | TB1.2/UCB0SOMI/UCB0SCL/TA1.0 |
| |
| P2.0 | Serial TX (to USB Debug) | TB2.0/UCA0TXD/UCA0SIMO/TB0CLK/ACLK | ||
| P2.1 | Serial RX (to USB Debug) | TB2.1/UCA0RXD/UCA0SOMI/TB0.0 | ||
| P2.2 | Wi-Fi SPI CLK | TB2.2/UCB0CLK/TB1.0 | ||
| P2.3 | Wi-Fi IRQ | TA0.0/UCA1STE/A6/CD10 | ||
| P2.4 | TA1.0/UCA1CLK/A7/CD11 | |||
| P2.5 | TB0.0/UCA1TXD/UCA1SIMO | |||
| P2.6 | TB1.0/UCA1RXD/UCA1SOMI | |||
| P2.7 | Power for NTC, LDR and Accelerometer | P2.7 | ||

| PJ4 | (Crystal - XIN) | (XIN) | ||
| PJ5 | (Crystal - XOUT) | (XOUT) |
Notes:
Only I/O pins shown
() - denotes Optionally used of Fraunchpad
LDR is not factory installed
Crystal is not factory installed (but is supplied with Fraunchpad)
