19 MEMORY DATA BIT ALLOCATION

Table 103 Memory data/bit allocation
19.1
19.1.1
The RGB outputs are analog signals derived from a DAC. The output impedance depends on the switched value, but is
low enough to drive the colour decoder.
The polarity and the delay between RGB outputs and the blanking output is programmable. The default setting is active
HIGH (RGB on).
