4. Variables Used in the Operation Descriptions of other Instructions, etc.
The following variables are used when describing the operation of DSP operation instructions for
which the DCT, DCF conditions can be designated.
In the above definitions, EX_DCT and EX_DCF are variables that become true when the DCT,
DCF conditions are designated in instructions. Refer to (1) DSP register definitions for
DSPDCBIT.
In DSP arithmetic operations, saturation processing is performed when the SR register’s saturation
bit is a 1. This saturation bit is called SBIT when describing the operations.
Additionally, the following function is defined to be used in common, to simplify the notation
when describing operations:
#define DSP_M_DST
#define DSP_M_DST_MSB
#define DSP_M_DSTG
#define DSP_M_DSTG_LSB8 DSP_MUL_Set.aa.dstg.lsb8
#define DSP_UNCONDITIONAL_UPDATE (!EX_DCT && !EX_DCF)
#define DSP_CONDITION_MATCH ((EX_DCT && DSPDCBIT) || (EX_DCF &&
!DSPDCBIT))
#define DSP_CONDITION_NOT_MATCH ((EX_DCT && !DSPDCBIT)||(EX_DCF &&
DSPDCBIT))
/* Function used in common in descriptions of DSP operation
instructions */
unsigned char carry_bit, borrow_bit, negative_bit, zero_bit,
overflow_bit;

{
*/
if(DSP_ALU_DSTG_BIT7==0) { /* positive value */
if(SBIT && overflow_bit) { /* Overflow Protection Enable & overflow
if((DSP_ALU_DSTG_LSB8!=0x0) || (DSP_ALU_DST_MSB!=0)) {
}
DSP_ALU_DSTG= 0x0;
DSP_ALU_DST = 0x7fffffff;
