UART Port 1 Serial Data Output: Serial data
output to the communication peripheral/modem
or data set for UART port 1. Upon reset, the TXD
pins will be set to MARKING condition (logic ‘1’
state).
UART Port 2 Serial Data Output: Serial data
output to the communication peripheral/modem
or data set for UART port 2. Upon reset, the TXD
pins will be set to MARKING condition (logic ‘1’
state).
GPIO IRQ Strap: This strap selects the interrupt
capabilities of some GPIO pins on the EP80579 .
The EP80579 interprets this strap as follows:
0 = GPIO IRQ capability enabled.
1 = GPIO IRQ capability disabled (default)

UART CLock: Input clock to the SIU. This clock is
passed to the baud clock generation logic for the
UART in the SIU. The clock can run at either
14.7456, 33, or 48 MHz.
