Signal Description
MPC5566 Microcontroller Reference Manual, Rev. 2
Freescale Semiconductor 2-21
2.3.2.5 External Address / Master Address Expansion / GPIO
ADDR[30:31]_ADDR[6:7]_GPIO[26:27]
ADDR[30:31]_ADDR[6:7]_GPIO[26:27] are the EBI address signals. Use the ADDR[6:7] alternate
signal functions to increase memory for master accesses; these signal cannot be used for slave accesses to
the chip.
2.3.2.6 External Data / GPIO
DATA[0:15]_GPIO[28:43]
DATA[0:15]_GPIO[28:43] are the EBI data signals for the first 16-bits.
2.3.2.7 External Data / Ethernet Transmit Clock / GPIO
DATA[16]_FEC_TX_CLK_GPIO[44]
DATA[16]_FEC_TX_CLK_GPIO[44] is an EBI data signal. The alternate signal is FEC transmit clock.
2.3.2.8 External Data / Ethernet Carrier Sense Data / GPIO
DATA[17]_FEC_CRS_GPIO[45]
DATA[17]_FEC_CRS_GPIO[45] is an EBI data signal. The alternate signal is FEC carrier sense data
function.
2.3.2.9 External Data / Ethernet Transmit Error / GPIO
DATA[18]_FEC_TX_ER_GPIO[46]
DATA[18]_FEC_TX_ER_GPIO[46] is an EBI data signal. The alternate signal is FEC transmit error.
2.3.2.10 External Data / Ethernet Receive Clock / GPIO
DATA[19]_FEC_RX_CLK_GPIO[47]
DATA[19]_FEC_RX_CLK_GPIO[47] is an EBI data signal. The alternate signal is FEC receive clock.
2.3.2.11 External Data / Ethernet Transmit Data / GPIO
DATA[20]_FEC_TXD[0]_GPIO[48]
DATA[20]_FEC_TXD[0]_GPIO[48] is an EBI data signal. The alternate signal is FEC transmit data [0]
function.
2.3.2.12 External Data / Ethernet Receive Error / GPIO
DATA[21]_FEC_RX_ER_GPIO[49]
DATA[21]_FEC_RX_ER_GPIO[49] is an EBI data signal. The alternate function is FEC receive error
function.
