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.
bi-directional
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 +7.5 Vdc.
in from target
Connect to logic that generates interrupts.
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 Vdd.
NC
Not Connected
NC
Not Connected
bi-directional
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.
bi-directional
Connect to MCU PTA0 pin. No other target-system logic
should be tied to this signal. Host I/O present on this pin.
bi-directional
Connect to user circuit that would normally be connected to
PTC0 on the MCU.
bi-directional
Connect to MCU PTC0 pin. No other target-system logic
should be tied to this signal. Grounded during reset and for
256 cycles after reset.
bi-directional
Connect to user circuit that would normally be connected to
PTC1 on the MCU.
bi-directional
Connect to MCU PTC1 pin. No other target-system logic
should be tied to this signal. Grounded during reset.
bi-directional
Connect to user circuit that would normally be connected to
PTC3 on the MCU.
bi-directional
Connect to MCU PTC3 pin. No other target-system logic
should be tied to this signal. Grounded during reset.
