D19 PC13 PC13 is used to select one of the DS3 _1 Loopback.
DS3_2 RT will be low if PC13 and PA1 will be low.
DS3_2 TR will be low if PC13 will be high and PA1 will be low.
D20 NC
D21 PC11
DS3-TXD3
DS3_2 TXD3 signal on FCC3
D22 PC10
MIIMDC
FE_(0,1,2) MIIMDC signal. The MDC signal is a GPIO that the user should configure for this
purpose. The TCOM SW has a program for this configuration. The PMC8260 dose not have a
special pin for MDC.
D23 PC9
MIIMDIO
FE_(0,1,2) MIIMDIO signal. The MDIO signal is a GPIO that the user should configure for this
purpose. The TCOM SW has a program for this configuration. The PMC8260 dose not have a
special pin for MDIO.
