LCD Data Bus—All LCD signals are driven low after reset and when LCD is off.
Frame Sync or Vsync—This signal also serves as the clock signal output for the gate
driver (dedicated signal SPS for Sharp panel HR-TFT).
Line pulse or H sync
Shift clock
Alternate crystal direction/output enable.
This signal is used to control the LCD bias voltage as contrast control.
Program horizontal scan direction (Sharp panel dedicated signal).
Control signal output for source driver (Sharp panel dedicated signal).
Start signal output for gate driver. This signal is an inverted version of PS (Sharp panel dedicated
signal).
Signal for common electrode driving signal preparation (Sharp panel dedicated signal).

SPI2 Master TxData Output—This signal is multiplexed with a GPI/O pin yet shows up as a primary
or alternative signal in the signal multiplex scheme table. Please refer to the SPI and GPIO chapters
in the MC9328MXL Reference Manual for information about how to bring this signal to the assigned
pin.
SPI2 Master RxData Input—This signal is multiplexed with a GPI/O pin yet shows up as a primary or
alternative signal in the signal multiplex scheme table. Please refer to the SPI and GPIO chapters in
the MC9328MXL Reference Manual for information about how to bring this signal to the assigned
pin.
