Details
This function returns result, which is value with a field of bits overwritten, starting at index. The
index specifies the position of the least significant bit of value. The width bits starting at index
are set to fieldValue.
The least significant bit of value is at index position 1; the most significant bit is at index position
32.
Before setting the field of bits, any fractional parts of value and fieldValue are truncated to form
integers.
If fieldValue is wider than width, the most significant bits of the fieldValue that exceed the
width are truncated. For example, if width is 4 bits and the binary value for fieldValue is 11110 (5
bits), the most significant bit of fieldValue is truncated and a binary value of 1110 is used.
Example
testResult = bit.setfield(15, 2, 3, 5)
print(testResult)
The binary equivalent of decimal 15 is 1111. After
overwriting it with a decimal 5 (binary 101) at index
position 2, the returned value is decimal 11 (binary
1011).

bit.test()
This function returns the Boolean value (true or false) of a bit at the specified index position.
Type TSP-Link accessible
Affected by Where saved Default value
Usage
result = bit.test(value, index)
Result of the bit manipulation
One-based bit position within value to test (1 to 32)
Details
This function returns result, which is the result of the tested bit.
The least significant bit of value is at index position 1; the most significant bit is at index position
32.
If the indexed bit for value is 0, result is false. If the bit of value at index is 1, the returned
value is true.
If index is bigger than the number of bits in value, the result is false.
