<Description>
• While this signal is “1,” the content of selected register is output in current value data area 1 or 2. At the same
time, the response to the data read command becomes “1.”

Data Data
• Data can be read from individual registers at the desired timing.
While the response to the data read command is “1,” this module continuously updates current value data areas 1
and 2.
Precautions:
• For the reading of the FIFO buffer, first-stage buffer data is output.
• When the FIFO buffer is empty, the value of both the target frequency FIFO buffer and command pulse count FIFO
buffer becomes “0” (zero).

Precautions:
• Numeric data is treated as binary data.
• The effective number of bits is determined by the bit width of each register.
The part exceeding the bit width of each register is ignored.
• For the number of effective bits for each register, refer to Paragraph 5-4.
• In position command mode, while the start command signal is “1,” set value data becomes as follows:
Lower word: (Not used)
Upper word: Position data (16-bit signed data)
In position command mode, while the start command is “1,” data writing in individual registers is disabled.
(The writing end signal is returned normally.)
