Input data format
Explanation of the data
(1)
Division data: For D
0
through D
15
(When S = 0, use D
4
through D
15
.)
Example: S = 0, SW = 0
When divide ratio = 1000, the actual set value is 500 since it passes through 1/2 the circuit. This translates to 1F4 (H)
in HEX notation, and to (MSB) 0000 0001 1111 0100 (LSB) in binary notation. This data is used from LSB to D0 through
D15.
Example: S = 1, SW = 1
When divide ratio = 1000, the actual set value is 1000 since it does not pass through 1/2 the circuit. This translates to
3E8 (H) in HEX notation, and to (MSB) 0000 0011 1110 1000 (LSB) in binary notation. This data is used from LSB to
D0 through D15.
Example: S = 1, SW = 0
When divide ratio = 1000, D0 through D3 can be anything since it does not pass through the prescalar. This translates
to 3E8 (H) in HEX notation, and to (MSB) 0001 1111 0100 (LSB) in binary notation. This data is used from LSB to D0
through D15.
