Description:
If the specified condition is true, the address of the instruction immediately following the BScc instruction
and the status register are pushed onto the stack. Program execution then continues at location PC+dis-
placement. The PC contains the address of the next instruction. If the specified condition is false, the PC
is incremented and program execution continues sequentially. The displacement is a 2's complement 32-
bit integer that represents the relative distance from the current PC to the destination PC. Short Displace-
ment, Long Displacement and Address Register PC Relative addressing modes may be used. The Short
Displacement 15-bit data is sign extended to form the PC relative displacement. See Section A.10 for
restrictions.
"cc" may specify the following conditions:
