VTR is an 8-bit write-only register that sets the threshold for the vertical sync signal when the
signal is detected from the composite sync signal. The threshold is set by bits 5 to 0 (VTR5 to
VTR0). Bits 7 and 6 are reserved. If a read is attempted, an undetermined value is read out. It is
initialized to H'C0 by a reset, or in stand-by or module stop mode.
