3.6.3.2
In addition to adder/subtracter saturation, writes to data
space can also be saturated, but without affecting the
contents of the source accumulator. The data space
write saturation logic block accepts a 16-bit, 1.15
fractional value from the round logic block as its input,
together with overflow status from the original source
(accumulator) and the 16-bit round adder. These inputs
are combined and used to select the appropriate
1.15 fractional value as output to write to data space
memory.
If the SATDW bit in the CORCON register is set, data
(after rounding or truncation) is tested for overflow and
adjusted accordingly:
• For input data greater than 0x007FFF, data
• For input data less than 0xFF8000, data written to
The Most Significant bit of the source (bit 39) is used to
determine the sign of the operand being tested.
If the SATDW bit in the CORCON register is not set, the
input data is always passed through unmodified under
all conditions.

The barrel shifter can perform up to 16-bit arithmetic or
logic right shifts, or up to 16-bit left shifts in a single
cycle. The source can be either of the two DSP
accumulators or the X bus (to support multi-bit shifts of
register or memory data).
The shifter requires a signed binary value to determine
both the magnitude (number of bits) and direction of the
shift operation. A positive value shifts the operand right.
A negative value shifts the operand left. A value of ‘0’
does not modify the operand.
The barrel shifter is 40 bits wide, thereby obtaining a
40-bit result for DSP shift operations and a 16-bit result
for MCU shift operations. Data from the X bus is
presented to the barrel shifter between bit positions 16
and 31 for right shifts, and between bit positions 0 and
16 for left shifts.
