AUTOMATIC ADJUSTMENT CD PREAMPLIFIER SERVO CONTROLLER
SERIAL COMMAND FUNCTION
An 8-bit shift register is installed in the logic controller to convert
(decode) serial data (MSD pin 25 ) from the microcomputer into a
command for the servo IC.
FUNCTION DESCRIPTION of Data-IN
Of the 8-bit data, high order 4 bits (D7 to D4) is used to select a
command mode and low-order 4 bits (D3 to D0) are used to set
(instruct) the command status.
Commands in the same mode can be given concurrently with data
transferred once. They are held until new data is entered.
Therefore, the command status is held if another mode is selected.
