PRODUCTION DATA.
Up to nine 8-bit I/O ports are implemented (see Table 6-52 through Table 6-56 for control and configuration registers):
NOTE
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 their module functions disabled. To enable the I/O functionality after a BOR reset, first configure the ports and then clear the LOCKLPM5 bit. For details, see the Configuration After Reset section of the Digital I/O chapter in the MSP430FR58xx, MSP430FR59xx, and MSP430FR6xx Family User's Guide.
