Ignore the 1 in bit2,
bit5, bit8, bit10, bit12
If multiple bits in the source address is 1, the low side is ignored, and if the source address is
0, the instruction will not be executed.
When the driver input is OFF, the instruction is not executed and the coding output is
unchanged.
When n ≤ 3, the high 8 bits in D0 are neglected.
When n=3, the encoding object has 2
3
= 8 bits, that is, bit7 ~ bit0 in D0. The encoding result
is stored in the lower 3 bits in D1, that is, bit2 ~ bit0.
When bit5 and bit2 in D0 are both 1, bit2 is ignored, and bit5 is coded, bit2-bit0 represent 5,
bit2 and bit0 are 1.

If the number of bits in the source address is 1, the low side is ignored, and if the source
address is 0, the instruction will not be executed.
When the driver input is OFF, the instruction is not executed and the coding output is
unchanged.
n = 4, the encoded object has 2

=16 bits, that is, bit15 ~ bit0 in D0. The encoding result is
stored in the lower 4 bits in D1, that is, bit3 ~ bit0.
The highest bit of 1 in D0 is bit14, ignoring all low bits 1, and encoding bit14, bit3-bit0
represent 14, bit3, bit2 and bit1 are 1.
