Sometimes the set of all 256 byte values is represented as a table 16x16, which gives easily readable hexadecimal codes for each value.

It takes the interrupt number formatted as a byte value.

It maps code point values to sequences of one or more byte values in a computer.

The byte values are in hex (base 16), so if "10" appears it isn't ten, it's sixteen.

Other formats are possible; 8 bits of data plus a parity bit can convey all 8-bit byte values.

These 17 byte values are as follows:

Each byte value is encoded by its index in a list of bytes, which changes over the course of the algorithm.

Code points from to are encoded in BOCU-1 as the corresponding byte value.

The byte values necessary to encode a given frequency in hertz are determined by the following formula:

Two situations are considered: 8-bit-clean environments, and environments that forbid use of byte values that have the high bit set.
