46.1.2 Modes of operation
The TCON has 3 operation modes:
• Bypass mode: the input signals are passed through, and the TCON shall be turned off
• TTL mode: the TCON is functional, driving parallel RGB output in non-RSDS mode, and the
TCON timing signals
• RSDS mode: the TCON is functional, driving the RSDS interface and timing signals
46.2 External signal descriptions
The TCON has the following external signals:
Table 46-1. TCON External Signals
