Pin Descriptions Pinout Information
2.2.8 Analog Display Port Pins
Table 2-8 provides detailed pin descriptions for the Analog Display Port.
DENR 108 O
Display pixel enable red. [Tri-state output, 4mA drive, 5V-tolerant]
DENG 106 O
Digital display pixel enable green. [Tri-state output, 4mA drive, 5V-tolerant]
DENB 107 O Digital display pixel enable blue. [Tri-state output, 4mA drive, 5V-tolerant]
DEN 145 I
Digital display output port output enable. [Input, pull-up, 5V-tolerant]
Active level controlled by DEN_POL [reg 0x61 bit 2].
Note: DEN only controls the data bus [DR(7:0), DG(7:0), DB(7:0)] and not the control
signals [DVS, DHS, DCLK, DENR, DENG, DENB].
DR0 132 O
Digital display output port red data. [Tri-state output, 4mA drive, 5V-tolerant]
DR1 133 O
DR2 135 O
DR3 136 O
DR4 138 O
DR5 139 O
DR6 141 O
DR7 142 O
DG0 121 O
Digital display output port green data. [Tri-state output, 4mA drive, 5V-tolerant]
DG1 122 O
DG2 124 O
DG3 125 O
DG4 127 O
DG5 128 O
DG6 129 O
DG7 130 O
DB0 110 O
Digital display output port blue data. [Tri-state output, 4mA drive, 5V-tolerant]
DB1 111 O
DB2 113 O
DB3 114 O
DB4 116 O
DB5 117 O
DB6 118 O
DB7 119 O
Table 2-8 Analog Display Port Pin Descriptions
Name Pin(s) Type Function
ADR 156 O Analog display port red (V/Pr) data.
ADG 153 O
Analog display port green (Y/Y) data.
ADB 150 O
Analog display port blue (U/Pb) data.
VREFIN 161 I Reference voltage input.
VREFOUT 162 O
Voltage reference output. This output nominally delivers 1.23v reference voltage from
bandgap reference block. It is normally connected to VREFIN pin.
