REGISTER 3-2: CORCON: CORE CONTROL REGISTER (CONTINUED)

bit 2

SFA: Stack Frame Active Status bit

1 = Stack frame is active; W14 and W15 address 0x0000 to 0xFFFF, regardless of DSRPAG and

DSWPAG values

0 = Stack frame is not active; W14 and W15 address of EDS or Base Data Space

bit 1

RND: Rounding Mode Select bit(1)

1 = Biased (conventional) rounding is enabled

0 = Unbiased (convergent) rounding is enabled

bit 0

IF: Integer or Fractional Multiplier Mode Select bit(1)

1 = Integer mode is enabled for DSP multiply

0 = Fractional mode is enabled for DSP multiply

Note 1:
