h_dspiabs
SYNTAX
FUNCTION
DESCRIPTION
stores the clipped value into rdest. All values are signed integers. This operation requires a zero as first argument.
The programmer is advised to use the unary pseudo operation
modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is not changed.
EXAMPLES

r30 = 0xffffffff
r10 = 0, r40 = 0x80000001
r20 = 1, r40 = 0x80000001

operation computes the absolute value of rsrc2, clips the result into the range [0x0..0x7fffffff], and
operation optionally takes a guard, specified in rguard. If a guard is present, its LSB controls the
