LBSC, MSIOF, I2C, SCIFA, SCIFB, QSPI, SCIF, HSCIF, PWM, TPU, GPIO (No.344 to 360): Up to 9-Function
Multiplexed and Mode Pins assigned (No.344, 345, 347, 348, 351)
These pins default function (function 1 or GPIO) after power-on reset depends on MD[3:1] pins setting except for
No.346 and 350 to 360 pins.

(No.346 and 350 to 360): These pins are set for GPIO even if MD[3:1] = 000 after power-on reset. For details,
refer to GPSR1, GPSR2 and GPSR5 registers in section 5, Pin Function Controller (PFC).
