description: |
|
|
Specifies the number of data nibbles. A nibble is a four-bit aggregation.
|
|
This property defines how many such nibbles are used in the data transmission.

|
required: true
|
|
description: |
|
|
Specifies the clock tick length in microseconds (us). This value determines the
|
|
base time unit for the system's timing operations, effectively setting the resolution
|
|
of the timer.

|
|
description: |
|
|
Specifies the successive calibration pulse check method options.
|
|
Option 1 is the preferred high-latency method, while option 2 provides
|
|
a low-latency alternative.
