2.10 Output Level Control Command
The
μ
PD6464A, 6465 can set the luminance level of the character and background (including the frame) by
using a command.
This command is a 2-byte command, and must be input in 16-bit units even when successively input.

Character level control bits
These bits can select two character luminance levels: 75 or 90 I.R.E.
If these bits are not set, the character level is set to 75 I.R.E.
Remark
The background (frame) level is fixed to 0 I.R.E.
Internal video signal amplitude control bit
This bit sets the amplitude of the internal video signal to 1 or 2 V
p-p
(this amplitude must match the amplitude of
the signal input in the external video signal mode). When the amplitude is set to 1 V
p-p
, the voltage applied to the
V
CNT
pin must be 2.5 V.
When the amplitude is set to 2 V
p-p
, apply 5 V to the V
CNT
pin.
