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
A-67
r30 = 0xffffffff
r10 = 0, r40 = 0x80000001
r20 = 1, r40 = 0x80000001
r50 = 0x80000000
