When PnADJ sets it as 0[h]-7[h]
The coefficient can be selected from 0 to 0.875 times.
The parameter value = The value written to EEPROM x PnADJ / 8
(This parameter value is set by high input of port driver.)
When an input port is “High”, the setting value is calculated by multiplying the parameter value written to
EEPROM by the coefficient of the following table.

For example) The value written to EEPROM = 60[h], PnADJ = 5[h]
In the case of Low : 60[h]
In the case of High : 60[h](96[d]) × 5[h](0.625) = 3C[h](60[d])
Thus, the parameter is changed as 60[h]/3C[h] by Low/High of port input.
When PnADJ sets it as 8 [h]-F[h]
The coefficient can be selected from 1.125 times to twice.
The parameter value = The value written to EEPROM x (PnADJ + 1) / 8
(This parameter value is set by high input of port driver.)
When an input port is “High”, the setting value is calculated by multiplying the parameter value written to
EEPROM by the coefficient of the following table.

For example) The value written to EEPROM = 59[h], PnADJ = A[h]
In the case of Low : 59[h]
In the case of High : 59[h](89[d]) × A[h](1.375) = 122.375[d] –> 122[d] = 7A[h]
Thus, the parameter is changed as 59[h]/7A[h] by Low/High of port input.
122.375[d] of an operation result turns into 122[d] by rounding-off processing.
*It is described later about rounding-off processing.
