bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15-10 Unimplemented: Read as ‘0’
bit 9 DPPINOE: Display Pin Output Pad Enable bit
DPPINOE is the master output enable and must be set to allow GDBEN<15:0>, DPENOE,
DPPWROE, DPVSOE and DPHSOE to enable the associated pads
1 = Enable display output pads
0 = Disable display output signals as set by GDBEN<15:0>
Pins used by the signals are assigned to the next enabled module that uses the same pins.
For data signals, GDBEN<15:0> can be used to disable or enable specific data signals while
DPPINOE is set.
bit 8 DPPOWER: Display Power-up Power-Down Sequencer Control bit
Refer to the “PIC24F Family Reference Manual”, Section 43. “Graphics Controller Module (GFX)”
for details.
1 = Set Display Power Sequencer Control port (GPWR) to ‘1’
0 = Set Power Control Sequencer signal (GPWR) ‘0’
bit 7 DPCLKPOL: Display Glass Clock (GCLK) Polarity bit
1 = Display latches data on the positive edge of GCLK
0 = Display latches data on the negative edge of GCLK
bit 6 DPENPOL: Display Enable Signal (GEN) Polarity bit
For TFT mode (DPMODE (G1CON2<2:0>) =
001):
1 = Active-high (GEN)
0 =Active-low (GEN
)
For STN mode (DPMODE (G1CON2<2:0>) =
010 or 011):
1 = GEN connects to the shift clock input of the display (Shift Clock mode)
0 = GEN connects to the MOD input of the display (Line/Frame Toggle mode)
bit 5 DPVSPOL: Display Vertical Synchronization (V
SYNC) Polarity bit
1 = Active-high (V
SYNC)
0 =Active-low (V
SYNC)
bit 4 DPHSPOL: Display Horizontal Synchronization (HSYNC) Polarity bit
1 = Active-high (HSYNC)
0 = Active-low (HSYNC
)
bit 3 DPPWROE: Display Power-up/Power-Down Sequencer Control port (GPWR) enable bit
1 = GPWR port is enabled (pin controlled by the DPPOWER bit (G1CON3<8>))
0 = GPWR port is disabled (pin can be used as an ordinary I/O)
bit 2 DPENOE: Display Enable Port Enable bit
1 = GEN port is enabled
0 = GEN port is disabled
