3.3.2.5
3.3.2.5.1
Read:Anytime.
Write:Anytime.
If the data direction bits of the associated I/O pins are set to 1, a read returns the value of the port register,
otherwise the value at the pins is read.
The EMAC MII external interface and IIC take precedence over general-purpose I/O function. If the
EMAC MII external interface is enabled in external PHY mode, PJ[3:0] pins become MII_MDC,
MII_MDIO, MII_CRS, MII_COL. If IIC is enabled, PJ[7:6] pins become IIC_SDA and IIC_SCL. Please
refer to the EMAC and IIC block description chapters for details.
3.3.2.5.2
Read:Anytime.
Write: writes to this register have no effect.
This register always reads back the status of the associated pins. This can be used to detect overload or
short circuit conditions on output pins.
