Description:
Bit 'b' in data memory location 'f' is
inverted. If 鈥榓(ch菐n)鈥� is 0, the Access Bank
will be selected, overriding the BSR
value. If 鈥榓(ch菐n)鈥� = 1, then the bank will be

Description:
If the Overflow bit is 鈥�1鈥�, then the
program will branch.
The 2鈥檚 complement number 鈥�2n鈥� is
added to the PC. Since the PC will
have incremented to fetch the next
instruction, the new address will be
PC+2+2n. This instruction is then
a two-cycle instruction.
