Addressing mode (see Chapter 5)
Multiply the signed 16-bit content of the T register by the signed 16-bit
contents of the location pointed to by the "loc16" addressing mode and store
the 32-bit result in the P register:
P = unsigned T * unsigned [loc16];
None
This instruction is not repeatable. If this instruction follows the RPT
instruction, it resets the repeat counter (RPTC) and executes only once.
