Datasheet
Pin Name
SEL_RXC/RXD1[7]
Pin
54
Type
I/O
Description
In SMII, SEL_RXC control the clock to output delay of RXD.
0: Clock out data on falling edge of receive clock
1: Clock out data on rising edge of receive clock
Recommended to set SEL_RXC=1.
(Pd)
In SS-SMII, SEL_RXC, must be set to 1.
SEL_TXC/RXD0[7]
55
I/O
(Pd)
In SMII, SEL_TXC control the clock to output delay of TXD.
0: Clock out data on falling edge of transmit clock
1: Clock out data on rising edge of transmit clock
Recommended to set SEL_TXC=1.
In SS-SMII, SEL_TXC, must be set to 1.
