There are SDRAM,FLASH,bootROM DPRAM link to the MPC8270 60x bus ,The number of memories and pins are as follows：
How to link those memorry to the 60x bus when it use as 60x-Bus Compatible Mode(TA as input in this mode)?
How to configure in uboot or in OS when I want to link the /BUSY(output) signal to the the TA(configure as input) pin of MPC8270 use as a mechanism to avoid read and write conflict of DPRAM ?
The TA(Transfer Acknowledge) only can be use in UPM mode? How about in GPCM mode?
