Appendices
The intermediate clock (SER_Clock) to be used in internal processing is also the same as the clock
frequency.
The following shows examples of the clock frequency settings to be used in BiSS-C.

Endat2.2 clock frequency is determined by the formula below.
Clock frequency (MHz) =
M = SerialClockMDiv
N = SerialClockNDiv
The intermediate clock (SER_Clock) to be used in internal processing is determined by the formula
below.

= $31 // Serial clock frequency = 2 MHz
= 0 // Serial clock frequency = 2 MHz
// Phase clock cycle used
= 0 // Rising edge used
= 0 // Delay set to 0
= $0B // BiSS-C selected
Name
Division factor of the serial clock
Division factor (exponent) of the serial clock
Always set 0.
Set which clock to do encoder reading on, phase or servo.
0: Phase clock
1: Servo clock
Selection of a serial trigger clock edge
Set which edge to start encoder reading at, the rising edge or falling edge of the
clock.
0: Rising edge
1: Falling edge
Setting of a delay from the serial trigger clock edge
Set the delay time between clock edge and encoder reading. The unit is an inter-
mediate clock (SER_Clock) cycle.
The setting range is from 0 to 255.
Serial encoder protocol setting
For Endat2.2, set it to $03.
