The SYNC command is a special operation which does not have a command code.
18 was HCS08 BDC command for TAGGO.
Each RD requires a delay between host read data byte and next read, command ends when target detects a soft-reset.
Each WD requires a delay between host write data byte and next byte, command ends when target detects a soft-reset.
HCS08 BDC had separate READ_CCR and READ_PC commands, the RS08 BDC combined this commands.
HCS08 BDC had separate WRITE_CCR and WRITE_PC commands, the RS08 BDC combined this commands.
6F is READ_SP (read stack pointer) for HCS08 BDC.
4F is WRITE_SP (write stack pointer) for HCS08 BDC.

Write accumulator (A)
Read the CCR bits z, c concatenated with
the 14-bit program counter (PC)
RD16=zc:PC
Write the CCR bits z, c concatenated with
the 14-bit program counter (PC)
WD16=zc:PC
Read the 14-bit shadow program counter
(SPC)
RD16=0:0:SPC
Write 14-bit shadow program counter
(SPC)
WD16 = x:x:SPC, the two most significant
bits shown by “x” are ignored by target
