Refer to I/O Type and Subscript Definition (Table 1).
(2)
This signal does not apply to the slave controller in a two controller system configuration. On the slave controller, this pin is reserved
and should be left unconnected. Refer to Typical Single Controller Chipset and Typical Two Controller Chipset for a description between
a one controller and a two controller configuration.

O5
Async
UART0, UART transmit data output. The firmware only
outputs debug messages on this port.
UART0_RXD
AD1
VDD33
I4
Async
UART0, UART receive data input. The firmware does not
support receiving data on this port.
UART0_RTSZ
AD2
VDD33
O5
Async
UART0, UART ready to send hardware flow control output
(active low)
UART0_CTSZ
AE2
VDD33
I4
Async
UART0, UART clear to send hardware flow control input
(active low). This pin requires an external 10 kΩ pulldown
resistor.

B9
Async
USB D– I/O
USB D+ I/O
HOLD_BOOTZ
F24
VDD33
B2
Async
Boot mode. When this pin is held low, the firmware boots-
up in bootload mode. When pin is held high, the firmware
boots-up in normal operating mode. This pin requires an
external 1 kΩ pullup resistor.
USB_ENZ (2)
E25
VDD33
B2
Async
The firmware will use this pin to enable an external buffer
on the USB data lines after it has completed initialization.
FAULT_STATUS
AC11
VDD33
O2
Async
This signal toggles or held high to indicate status faults.
HEARTBEAT
AB12
VDD33
O2
Async
This signal toggles to indicate the system is operational.
Period is approximately 1 second.
SEQ_INT2
H26
VDD33
I2
Async
This signal serves as an interrupt for pattern sequencing
and must be connected to SEQ_AUX6.
