295 / 1386 page  The 60x Bus MPC8280 PowerQUICC II Family Reference Manual, Rev. 1 Freescale Semiconductor 8-19 extended transfers. These transactions are compatible with the 60x bus, but some slaves or masters do not support these features. Clear BCR[ETM] to disable this type of transaction. This places the MPC8280 in strict 60x bus mode. The following tables are extensions to Table 8-7, Table 8-8, and Table 8-9. Table 8-10 lists the patterns of the extended data transfer for write cycles when MPC8280 initiates an access. Note that 16- and 24-byte transfers are always eight-byte aligned and use a 64-bit or less port size. Table 8-11 lists the bytes required on the data bus for extended read cycles. Note that 16- and 24-byte transfers are always 8-byte aligned and use a maximum 64-bit port size. Table 8-10.
