* LONG_MPY controls whether or not the instruction set has:

* (if not defined)
|
|
* LDIHI - load the value into the upper 16 bits of a register
|
|
* MPYS - Multiplies two 16-bit values into a signed 32-bit result
|
|
* MPYU - Multiplies two 16-bit values into an unsigned 32-bit result
|
|
* (if defined)
|
|
* MPY - Multiplies two 32-bit values and returns the lower 32-bits of
|
|
* the result. Works for signed and unsigned values.

|
* MPYSHI - Multiplies two 32-bit values and returns the upper 32-bits of
