Table E−2 lists the C2xLP instructions with the C28x equivalent syntax. The
C28x assembler will accept either the C2xLP syntax or the equivalent C28x
syntax. The disassembler will decode and display the C28x syntax.
The C2xLP cycle count numbers shown are for zero wait-state internal
memory, where n equals the number of repetitions (i.e., if an instruction is re-
peated, using the RPT instruction for repeatable instructions, n times it is exe-
cuted n+1 times).
