Direction
Out to target Connect to logic that is to receive the RST signal.
Ground Connect to ground (V
In from target Connect to all logic that generates resets.
Connect to MCU RST pin and P1 pin 1. No other target-system
Bidirectional
logic should be tied to this signal. It will swing from 0 to +7.5 Vdc.
In from target Connect to logic that generates interrupts.
Connect to MCU IRQ pin. No other target-system logic should be
Out to target
tied to this signal. It will swing from 0 to +7.5 Vdc.
Connect to user circuit that would normally be connected to PTA0
Bidirectional on the MCU. This circuit will not be connected to the MCU when
the in-circuit simulator is being used.
Connect to MCU PTA0 pin. No other target-system logic should be
Bidirectional
tied to this signal. Host I/O present on this pin.
Connect to user circuit that normally would be connected to PTB0
Bidirectional
on the MCU.
Connect to MCU PTB0 pin. No other target-system logic should be
Bidirectional tied to this signal. Grounded during reset and for 256 cycles after
reset.
Connect to user circuit that normally would be connected to PTB2
Bidirectional
on the MCU.
Connect to MCU PTB2 pin. No other target-system logic should be
Bidirectional
tied to this signal. Held at +5 Vdc during reset.
Connect to user circuit that normally would be connected to PTB3
Bidirectional
on the MCU.
Connect to MCU PTB3 pin. No other target-system logic should be
Bidirectional
tied to this signal. Grounded during reset.
