Description:
If the specified condition is true, program execution continues at location PC+displacement. The PC con-
tains 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 rep-
resents the relative distance from the current PC to the destination PC. Short Displacement, Long Dis-
placement 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:
