VPCTL1 to 0, VP7 to 0
The pitch of variable pitch mode is set.
The setting in variable pitch mode is as shown below.
The setting of the pitch can be expressed with the equation below.
P = [%]
–n
10
P: Setting value of pitch
n: Setting value for VPCTL1, VPCTL0 and VP7 to VP0 (two's complementary,
VPCTL1 is sign bit)
The setting range of the pitch is –48.7 to +51.2%.
The pitch setting for + side should be within the playback speed of the recommended operating conditions.
The following is the example of the command in variable pitch mode.
$EX001
(Sets to CLV-N mode. The INV VPCO is set to 1.)
$AE4XX
(Sets to use variable pitch mode)
WAIT
(Wait time for VCO2 pull-in: until VCTL stabilizes.)
$AECXX
(Variable pitch mode is turned on. The VCO2 is the reference to the internal clock.)
$D60A00
(The pitch is set to -1.0%)
$D60000
(The pitch is set to 0.0%)
$AE4XX
(Variable pitch mode is turned off. The crystal is the reference to the internal clock.)
