you send and places them in the X or Y
register. The format is exponent first,
followed by the mantissa (most significant
bit first). You can also load integers or
IEEE format numbers for conversion using
this command.
MUL
Multiplies X and Y leaving the result in X.
Y is unchanged. This command may take
approximately 240uS in the worst case.
OPT
Sets options. Send the option byte after this
command. Using $80 turns on saturation
(which represents over and underflows as
minimum and maximum values). Using
$40 enables rounding. If this option is not
on, results are truncated which is faster, but
less accurate. On a power up reset, both
flags are off.
RCL0, RCL1
Recalls register 0 or 1 to X. The register is
unchanged.
READX
This command sends the four bytes that
comprise the X register to the host. The
host must clock in 4 bytes. The first byte
will be the exponent, and the following
three bytes the mantissa (MSB first). Note
that if you execute an IEEECVT command
