Freescale Semiconductor
80-Pin
RGPIO_ENB selects between standard GPIO and RGPIO. When PTD6 is set as RGPIO output, and "1" is driven to PTD6 via
RGPIO function, a read of register RGPIODATA6 always returns a "0" because V1 RGPIO design looks for IO enable when the
return value of RGPIO function reads data. As PTD6 is set to RGPIO output only, it returns "0" always to RGPIODATA6, athough
PTD6 pin is driven to high.
