SW Reset

The software reset is invoked by writing to its register. The software reset synchronizes all internal

states. After power on reset the TCON module remains in this "sw reset active" state.

It is deasserted by internal logic synchronous to internal video synchronization signals, that means

last pixel of video frame (inclusive blanking). After configuring TCON it is therefore necessary to setup

the video frame (HTP, VTP, HDP, VDP) in module DISP to provide a valid video frame to TCON

module. Otherwise no RGB and display clock data is output.

Configuration registers are not reseted by SW reset, only internal states of TCON.
