Notes:
1.All multiplexed signals are listed only once and do not re-occur. For example, LCS5/DMA_REQ2 is listed only once in the
Local Bus Controller Interface section, and is not mentioned in the DMA section even though the pin also functions as
DMA_REQ2.
2.Recommend a weak pull-up resistor (2–10 K
Ω) be placed on this pin to OVDD.
3.This pin must always be pulled high.
4.This pin is a reset configuration pin. It has a weak internal pull-up P-FET which is enabled only when the processor is in the
reset state. This pull-up is designed such that it can be overpowered by an external 4.7-k
Ω pull-down resistor. However, if
the signal is intended to be high after reset, and if there is any device on the net which might pull down the value of the net
at reset, then a pull-up or active driver is needed. TSEC3_TXD[3] (cfg_srds_sgmii_refclk) is an exception, because the
default value of this configuration signal is low (0). Thus, no external pull-down resistor is needed for selecting the default
configuration value.
5. Treat these pins as no connects (NC) unless using debug address functionality.
