Rn = Bset Rx By Ry|<Data8> - Analog Devices ADSP-2106x SHARC User Manual

Compute Operations
Syntax:
Rn = BSET Rx BY Ry
Rn = BSET Rx BY <data8>
Function:
Sets a bit in the fixed-point operand in register Rx. The result is placed in
the fixed-point field of register Rn. The floating-point extension field of Rn
is set to all 0s. The position of the bit is the 32-bit value in register Ry or
the 8-bit immediate value in the instruction. The 8-bit immediate data can
take values between 31 and 0 inclusive, allowing for any bit within a 32-bit
field to be set. If the bit position value is greater than 31 or less than 0, no
bits are set.
Status flags:
SZ Is set if the output operand is 0, otherwise cleared
SV Is set if the bit position is greater than 31, otherwise cleared
SS Is cleared
Note: This compute operation affects a bit in a register file location. There
is also a bit manipulation instruction that affects one or more bits in a
system register. This BIT SET instruction should not be confused with the
BSET shifter operation. See Appendix E for more information on BIT SET.
