COAG_DOWN
This is an input signal to the system logic from the front panel overlay to decrease the
power setting for Coagulation and Fulguration coag modes.
COAG_UP
This is an input signal to the system logic from the front panel overlay to increase the
power setting for Coagulation and Fulguration coag modes.
BIPOLAR_DOWN
This is an input signal to the system logic from the front overlay to decrease the power
setting for the Bipolar mode.
BIPOLAR_UP
This is an input signal to the system logic from the front overlay to decrease the power
setting for the Bipolar mode.
LED_SEL0
This is an output signal from the system logic to the display circuit for controlling the
LED’s on the front panel.
LED_SEL_1
This is an output signal from the system logic to the display circuit for controlling the
LED’s on the front panel.
BLEND_LED_SEL_0
This is an output signal from the system logic to the display circuit for controlling the
LED’s on the Blend bar.
BLEND_LED_SEL_1
This is an output signal from the system logic to the display circuit for controlling the
LED’s on the Blend bar.
A/D_0 – A/D_7
These are data lines between the system logic and the A/D for sensing voltage levels,
impedance and current.
A/D_CLK This is an output clock signal from the system logic to the A/D.
A/D_SELECT
This is an output signal from the system logic to control the channel that is being
converted from analog to digital information.
CS_A/D_IV This is a communication line used by the system logic to control the sensing A/D’s.
CS_A/D_L This is a communication line used by the system logic to control the sensing A/D’s.
CS_A/D_BACKUP This is a communication line used by the system logic to control the sensing A/D’s
A/D_SLEEP This is a communication line used by the system logic to control the sensing A/D’s.
TEST_MUX_0 – TEST_MUX_2 This is a communication line used by the system logic to control the sensing A/D’s.
