Pin names in bold text in the table replace the plain-text-named
functions when Mode C = 1. A + sign separates two functions
when either function can be active for either major I/O mode.

value of the pin at the deassertion of RESET. The multiplexed
pins DT1/FO, TFS1/IRQ1, RFS1/IRQ0, and DR1/FI, are mode
selectable by setting Bit 10 (SPORT1 configure) of the System
Control Register. If Bit 10 = 1, these pins have serial port func-
tionality. If Bit 10 = 0, these pins are the external interrupt and
flag pins. This bit is set to 1 by default, upon reset.
