These signals do not apply to the slave controller in a two controller system configuration. On the slave controller, these pins are
reserved and should be left unconnected. Refer to the Typical Single Controller Chipset and the Typical Two Controller Chipset for a
description between a one controller and a two controller configuration.

TRIG_IN_1
AF7
VDD33
I4
Async
In video pattern mode, this signal is used for advancing the
pattern display.
TRIG_IN_2
H25
VDD33
I2
Async
In video pattern mode, the rising edge of this signal is used
for starting the pattern display and the falling edge is used
for stopping the pattern display. It works along with the
software start stop command.
TRIG_OUT_1
E20
VDD33
O2
Async
Active high trigger output signal during pattern exposure.
TRIG_OUT_2
D22
VDD33
O2
Async
Active high trigger output to indicate first pattern display.

SEQ_SYNC
AB9
VDD33
B3
Async
Sequence sync. This signal must be connected between the
master and slave controller in a two controller configuration.
Do not leave unconnected. This pin requires an external 10-
kΩ pullup resistor.
SSP0_CSZ4_SLV
U26
VDD33
B2
SSP0_CLK
This signal is used by the master controller to communicate
with the slave controller over the SSP interface. This pin
requires an external 4.7-kΩ pullup resistor.
FSD12_OUTPUT
T23
VDD33
B2
Async
This pin must be connected to DA_SYNC_INPUT (3)
DA_SYNC_INPUT
R22
VDD33
B2
Async
This pin must be connected to FSD12_OUTPUT (4)
SLV_CTRL_PRST
V25
VDD33
B2
Async
This signal must be connected between the master and
slave controller in a two controller configuration. The slave
controller will pull this signal high to inform the master
controller that it is present and ready. This pin requires an
external 10-kΩ pulldown resistor. Do not leave unconnected.
CTRL_MODE_CF
G
V26
VDD33
B2
Async
When this pin is high, the controller operates as the master
controller. When this pin is low the controller operates as the
slave controller. Use an external 4.7-kΩ pullup or pulldown
resistor to identify the controller. Do not leave unconnected.
