PRODUCTION DATA
Up to 60 I/O ports are implemented.
Configuration of digital I/Os after BOR reset
To prevent any cross currents during start-up of the device, all port pins are high-impedance with Schmitt triggers and module functions disabled. To enable the I/O functions after a BOR reset, the ports must be configured first and then the LOCKLPM5 bit must be cleared. For details, see the Configuration After Reset section in the Digital I/O chapter of the MSP430FR4xx and MSP430FR2xx Family User's Guide.
