The TM5250 CPU on the PNX17xx Series both support 8, 16 and 32-bit data types
and a memory system that is byte addressable. The CPU support a big-endian and
little-endian mode of operation. The effect of a CPU store instruction on memory is
defined in
quantity contained in the 16 lsbits of the CPU register. And the memory locations
affected are “a” and “a+1.” But which byte goes where is dependent upon endian
mode.
Table 1: Memory Result of a Store to Address ‘a’ Instruction
The effect of a CPU load instruction on a register is defined for unsigned and signed
loads in
In the case of an unsigned load, higher order bits are filled with zeroes. In the case of
a signed load, higher order bits are filled with the sign bit of the data item loaded.
