condition. In addition, the Ethernet NPE uses internal control state to prevent repetitive
flushing of the MAC Rx Engine FIFO.
No Fix.
Incorrect Strapping Configuration during Bootup
The EX_ADDR[23:0] has a strong pull-up resistor attached internally. During bootup,
the strapping value will be read incorrectly when the EX_ADDR[23:0] is attached to
1K ohm pull-down resistor.
Incorrect strapping configuration will be read during bootup.
A 470 ohm pull-down is required to override the internal pull-up resistor.
No Fix.
Strong Pull-up Resistor Attached to the JTG_TRST_N
The JTG_RST_N has a strong pull-up resistor attached internally. During bootup, the
IEEE 1149.1 JTAG interface is unable to detect a ‘low’ at the JTG_TRST_N pin when it is
attached to a 10K ohm pull-down resistor.
Intermittent bootup problem.
A 100 ohm pull-down is required to override the internal pull-up resistor.
No Fix.
