Notes:
»
Signal SER0_1_MEZ_KILL# should be tied low on the I/O Module if the I/O Module intends to drive any of the
SER0 or SER1 lines. Tying SER0_1_MEZ_KILL# low disables the Evaluation Carrier Serial Port 0 and 1
transceiver.
»
Signal SER2_3_MEZ_KILL# should be tied low on the I/O Module if the I/O Module intends to drive any of the
SER2 or SER3 lines. Tying SER2_3_MEZ_KILL# low disables the Evaluation Carrier Serial Port 2 and 3
transceivers.
»
The I/O Module should use V_IO for its I/O buffers. Per the SMARC specification, V_IO may be 1.8V or 3.3V, with
most systems using 1.8V I/O.
