(2) Bit manipulation addressing instruction codes
pmem.@L, and @H+mem.bit.
The table below lists the second byte *2 of an instruction code corresponding to the above addressing.
Bn: Immediate data for bit
Fn:
Gn: Immediate data for pmem (Bits 2 to 5 of address)
Dn: Immediate data for mem (Low-order four bits of address)
*1 in the operand field indicates that there are three types of bit manipulation addressing, fmem.bit,
