Request a timed reference pulse to determine
target BDC communication speed
Enable acknowledge protocol. Refer to
Freescale document order no. HCS08RMv1/D.
Disable acknowledge protocol. Refer to
Freescale document order no. HCS08RMv1/D.
Enter active background mode if enabled
(ignore if ENBDM bit equals 0)
Read BDC status from BDCSCR
Write BDC controls in BDCSCR
Read a byte from target memory
Read a byte and report status
Re-read byte from address just read and
report status
Write a byte to target memory
Write a byte and report status
Read BDCBKPT breakpoint register
Write BDCBKPT breakpoint register
Go to execute the user application program
starting at the address currently in the PC
Trace 1 user instruction at the address in the
PC, then return to active background mode
Same as GO but enable external tagging
(HCS08 devices have no external tagging pin)
Read accumulator (A)
Read condition code register (CCR)
Read program counter (PC)
Read H and X register pair (H:X)
Read stack pointer (SP)
Increment H:X by one then read memory byte
located at H:X
Increment H:X by one then read memory byte
located at H:X. Report status and data.
