4/17/98 6-67 Addressing Modes and Data Types
BLE Branch if less than or equal (signed)
Syntax: BLE rel8
Operation: (PC) <-- (PC) + 2
if ((Z) OR (N)) XOR (V) = 1 then
(PC) <-- (PC + rel8*2)
(PC.0) <-- 0
Description: The branch is taken if the last compare instruction had a destination value that was
less than or equal to the source value, in a signed operation. The branch range is +254 bytes to -
256 bytes, with the limitation that the target address is word aligned in code memory.
Note: Refer to section 6.3 for details of branch range
