Signal Description
MPC5566 Microcontroller Reference Manual, Rev. 2
Freescale Semiconductor 2-23
2.3.2.21 External Data / Ethernet Receive Data / GPIO
DATA[30]_FEC_RXD[2]_GPIO[58]
DATA[30]_FEC_RXD[2]_GPIO[58] is an EBI data signal.The alternate function is FEC receive data [2].
2.3.2.22 External Data / Ethernet Receive Data / GPIO
DATA[31]_FEC_RXD[3]_GPIO[59]
DATA[31]_FEC_RXD[3]_GPIO[59] is an EBI data signal.The alternate function is FEC receive data [3].
2.3.2.23 External Master Bus / GPIO
TSIZ[0:1]_GPIO[60:61]
TSIZ[0:1]_GPIO[60:61] indicate the size of an external bus transfer when in external master or slave mode
operation. The TSIZ[0:1] signals are not driven by the EBI in single master operation.
2.3.2.24 External Read/Write / GPIO
RD_WR_GPIO[62]
RD_WR_GPIO[62] indicates whether an external bus transfer is a read or write operation.
2.3.2.25 External Burst Data In Progress / GPIO
BDIP_GPIO[63]
BDIP_GPIO[63] indicates that an EBI burst transfer is in progress.
2.3.2.26 External Write/Byte Enable / GPIO
WE/BE[0:3]_GPIO[64:67]
WE/BE[0:3]_GPIO[64:67] specify which data pins contain valid data for an external bus transfer.
2.3.2.27 External Output Enable / GPIO
OE_GPIO[68]
OE_GPIO[68] indicates that the EBI is ready to accept read data.
2.3.2.28 External Transfer Start / GPIO
TS_GPIO[69]
TS_GPIO[69] is asserted by the EBI owner to indicate the start of a transfer.
2.3.2.29 External Transfer Acknowledge / GPIO
TA_GPIO[70]
TA_GPIO[70] is asserted by the EBI owner to acknowledge that the slave has completed the current
transfer.
