Indirect, Auto-Increment mode: Call a subroutine at the 20-bit address contained in the

words pointed to by register R5 and increment the 20-bit address in R5 afterwards by 4.

The next time the S/W flow uses R5 as a pointer, it can alter the program execution due

to access to the next word address in the table pointed to by R5. Indirect, indirect R5.

CALLA @R5+ ; Start address at @R5. R5 + 4

Indexed mode: Call a subroutine at the 20-bit address contained in the address pointed

to by register (R5 + X); for example, a table with addresses starting at X. (R5 + X)

points to the LSBs, (R5 + X + 2) points to the MSBs of the word address. X is within R5

+ 32 K. Indirect, indirect (R5 + X).

CALLA X(R5) ; Start address at @(R5+X). z16(R5)
