ST7 addressing mode overview (continued)
At the time the instruction is executed, the Program Counter (PC) points to the instruction
following JRxx.
Inherent mode
All Inherent instructions consist of a single byte. The opcode fully specifies all the required
information for the CPU to process the operation.
