### Code Type 0xC0: Begin Register Conditional Block
|
||||
|
||||
Code type 0xC0 performs a comparison of the contents of a register and another value. This code support multiple operand types, see below.
|
||||
|
||||
If the condition is not met, all instructions until the appropriate conditional block terminator are skipped.
