3.2.1.5
The CCR is the LSB of the processor status register (SR). Bits 4–0 act as indicator flags for results
generated by processor operations. Bit 4, the extend bit (X bit), is also used as an input operand
during multiprecision arithmetic computations.
3.2.2
The registers in the EMAC portion of the user programming model, are described in
“Enhanced Multiply-Accumulate Unit
3-4
• Four 48-bit accumulator registers partitioned as follows:
• Eight 8-bit accumulator extensions (two per accumulator), packaged as two 32-bit values
• One 16-bit mask register (MASK)
— Four 32-bit accumulators (ACC0–ACC3)
— Eight 8-bit accumulator extension bytes (two per accumulator). These are grouped into
Accumulators and extension bytes can be loaded, copied, and stored, and results from
EMAC arithmetic operations generally affect the entire 48-bit destination.
for load and store operations (ACCext01 and ACCext23)

Reserved, should be cleared
Extend condition code bit. Set to the value of the C-bit for arithmetic operations;
otherwise not affected or set to a specified result.
Negative condition code bit. Set if the most significant bit of the result is set;
otherwise cleared.
Zero condition code bit. Set if the result equals zero; otherwise cleared.
Overflow condition code bit. Set if an arithmetic overflow occurs implying that the
result cannot be represented in the operand size; otherwise cleared.
Carry condition code bit. Set if a carry out of the operand msb occurs for an
addition, or if a borrow occurs in a subtraction; otherwise cleared
Set to the value of the C bit for arithmetic operations; otherwise not affected.
