In mpc5200B, we have configured Ethernet port (bit 12:15) of GPS PORT Configuration Register (MBAR + 0B00h) as 1010 (i,e. Two UARTes, J1850).
While in this configuration, we are not using ETH_8, ETH_15 & ETH_16 pins for its specified functionality i.e, UART5e_CD, UART4_CTS & UART4_CD respectively. Rather, we want to use these pins as GPIO, i.e, we want to read and write from/to these pins as in GPIO configuration without configuring Ethernet port (bit 12:15) of GPS PORT Configuration Register (MBAR + 0B00h) as 0000 (i.e, GPIO).
Could you please suggest us the method to achieve that?
