Default Value
Default Value
CGMS-A Data is set which is super-imposed on Y output of HD
signal.
Data to be set are CGMS1 ~ CGMS6.
CGMS7 ~ CGMS14 should be set at CGMS Data 2 Register
write “ 0 “.
This bit is set when CGMS-A signal is to be super-imposed on Y
output of HD signal.
Target Line to be super-imposed with, is automatically decided
by setting [ MODE1 : MODE0 ]-bits.
0 : CGMS-A function is “ OFF “.
1 : CGMS-A signal is super-imposed.
CGMS-A Data is set which is super-imposed on Y output of HD
signal.
Data to be set are CGMS7 ~ CGMS14.
CGMS1 ~ CGMS6 should be set at CGMS Data 1 Register.
