Target System Connection
1
RST-OUT
Out to target
Connect to logic that is to receive the RST signal.
2
GND
Ground
Connect to ground (V
SS
).
3
RST-IN
In from target
Connect to all logic that generates resets.
4
RST
Bidirectional
Connect to MCU RST pin and P1 pin 1. No other target-system
logic should be tied to this signal. It will swing from 0 to +8.6 Vdc.
5
TGT-IRQ
In from target
Connect to logic that generates interrupts.
6
IRQ
Out to target
Connect to MCU IRQ pin. No other target-system logic should be
tied to this signal. It will swing from 0 to +8.6 Vdc.
7
TGT-PTA0
Bidirectional
Connect to user circuit that would normally be connected to PTA0
on the MCU. This circuit will not be connected to the MCU when
the in-circuit simulator is being used.
8
PTA0
Bidirectional
Connect to MCU PTA0 pin. No other target-system logic should be
tied to this signal. Host I/O present on this pin.
9
TGT-PTB0
Bidirectional
Connect to user circuit that normally would be connected to PTB0
on the MCU.
10
PTB0
Bidirectional
Connect to MCU PTB0 pin. No other target-system logic should be
tied to this signal. Grounded during reset and for 256 cycles after
reset.
11
TGT-PTB2
Bidirectional
Connect to user circuit that normally would be connected to PTB2
on the MCU.
12
PTB2
Bidirectional
Connect to MCU PTB2 pin. No other target-system logic should be
tied to this signal. Held at +5 Vdc during reset.
13
TGT-PTB3
Bidirectional
Connect to user circuit that normally would be connected to PTB3
on the MCU.
14
PTB3
Bidirectional
Connect to MCU PTB3 pin. No other target-system logic should be
tied to this signal. Grounded during reset.
