Hi, I'm using the LG32 and wish to use GPIO pins as full complementary driver. According to the LG32 manual:
"Pins that have shared function with the LCD have special behavior based on the state of the VSUPPLY bits in the LCDSUPPLY register. These pins (PTA, PTB, PTC[4:0], PTD, PTE and PTG) can operate as full complementary drive or open drain drive depending on the VSUPPLY bits. When VLL3 is connected to VDD externally, VSUPPLY = 11, FCDEN = 1, and RVEN = 0; the pins operate as full complementary drive. For all other VSUPPLY modes, the GPIO shared with LCD operates as open drain. "
My problem is that I am unable to change the VSUPPLY to 11 or FCDEN to 1 (RVEN=0 by default). When attempting to change these values in CodeWarrior using the memory window, my new values are not accepted. I also cannot change the values in code. I have also tried jumpering VLL3 to VDD externally and re-booting the board....still no success.
Any suggestions welcome.
