1. The A5H opcode is not used by the original set of ASM51 instructions. In Core8051, this opcode is used to implement a trap instruction
for the OCI debugger logic.
Instruction Definitions
All Core8051 core instructions can be condensed to 53 basic operations, alphabetically ordered according to the
operation mnemonic section, as shown in Table 17 .
