2) SYNC width adjustment (H-lock PLL mode only) of horizontal sync output (HSOUT)
Registers related to SYNC width adjustment of HSOUT
Name
Functions
Sub address
bit width
HSPLLSEL
This register selects the horizontal sync signal (SHOUT) in the H-lock PLL mode.
0: HSIN
1: This is the signal that is fed back to the phase detector after dividing the VCO output
of the PLL.
*: SYNC width adjustment for HSOUT must be turned on when HSPLLSEL is set to 1.
0x01
1
CORREN
This register turns on and off the SYNC width adjustment for HSOUT.
0: OFF, 1: ON
0x27

CORRHSS
SYNC width adjustment register for HSOUT (to be described below)

CORRHSE
SYNC width adjustment register for HSOUT (to be described below)

When "1" is set for HSPLLSEL in the H lock PLL mode, the horizontal sync output signal is not HSIN but the signal
that is fed back to the phase detector after dividing the VCO output of the PLL. The duty ratio of this signal is 50%,
which means when it is to be used as the horizontal sync signal, the sync width must be determined. Furthermore, if "0"
is set for HSPLLSEL, the horizontal sync input (HSIN) signal can be output in its original form even in the H lock PLL
mode.
*1: Clock is expressed in units of CLKOUT1.
*2: A value equivalent to about three-fourths of one HSOUT period (640 or so with the NTSC system) must be set as
the CORRHSE[11:0] value.
