Details
The binary equivalent of the returned value indicates the value of the input lines on the I/O port. The least
significant bit (0) of the binary number corresponds to Line 1. Bit 13 corresponds to Line 14.
For example, a returned value of 170 has a binary equivalent of 00000010101010, which indicates that Lines 2,
4, 6, and 8 are high (1), and the other 10 lines are low (0).

Assume line 4 is set high, and it is then read.
Output:
1.0000000e+00
Where saved Default value
Assume Lines 2, 4, 6, and 8 are set high when
the I/O port is read.
