6.2
A single-wire interface pin is used to communicate with the BDM system. Two additional pins are used
for instruction tagging. These pins are part of the multiplexed external bus interface (MEBI) sub-block and
all interfacing between the MEBI and BDM is done within the core interface boundary. Functional
descriptions of the pins are provided below for completeness.
6.2.1
Debugging control logic communicates with external devices serially via the single-wire background
interface pin (BKGD). During reset, this pin is a mode select input which selects between normal and
special modes of operation. After reset, this pin becomes the dedicated serial interface pin for the
background debug mode.
6.2.2
This pin is used to tag the high byte of an instruction. When instruction tagging is on, a logic 0 at the falling
edge of the external clock (ECLK) tags the high half of the instruction word being read into the instruction
queue.
6.2.3
This pin is used to tag the low byte of an instruction. When instruction tagging is on and low strobe is
enabled, a logic 0 at the falling edge of the external clock (ECLK) tags the low half of the instruction word
being read into the instruction queue.

BKGD — Background interface pin
TAGHI — High byte instruction tagging pin
TAGLO — Low byte instruction tagging pin
BKGD and TAGHI share the same pin.
TAGLO and LSTRB share the same pin.
External Signal Description
BKGD — Background Interface Pin
TAGHI — High Byte Instruction Tagging Pin
TAGLO — Low Byte Instruction Tagging Pin
Generally these pins are shared as described, but it is best to check the
device overview chapter to make certain. All MCUs at the time of this
writing have followed this pin sharing scheme.
