XT4D, XT2D:
MCK (digital servo master clock) frequency division setting
This command forcibly sets the frequency division ratio to 1/4, 1/2 or 1/1 when MCK is
generated. See the description of $3E for XT1D. Also, see the decription of "§5-2. Digital
Servo Block Master Clock (MCK)".
AGG4:
This varies the amplitude of the internally generated sine wave using the AGGF and AGGT
commands during AGC. When AGG4 = 0, the default is used. When AGG4 = 1, the setting is
as shown in the table below.
