Section 4 Detailed Description
(2) 2-bit NRZ output method
Data are sequentially output by 2-bit into the Data 2
1
Output and the Data 2
0
Output starting from the specified first
delivery address LSB for the specified data bit length (an even number). This is used when the 4-value FSK modulation
is performed in the combination with the FSK encoder.

Note:
When the specified data bit length is an odd number, the delivery is made of which bit length is 1-bit subtracted
from the specified bit length (an even number). When you want to output an odd bit length data by 2-bit NRZ
output method, continuously write the same data twice to make the total bit length to be an even number before
the delivery.
Example) In the case of the seven-bit data “0100101” delivery by using the 2-bit NRZ output:
Deliver the data to be 14-bit data “01001010100101”.
