MPC860 and Compact Flash Card in True Ide Mode

hello ,

Dan wrote in returning SangTae Ha "MPC850 and ATA/IDE"

There are at least three easy and inexpensive ways people add ATA/IDE
to the 8xx processors for embedded systems:

Connect to PCMCIA interface
Use a simple CPLD between the processor bus and disk
Program one of the UPMs to generate timing and then
externally buffer the signals

I use the third way (UPMB) to add ATA/IDE (SanDisk 16M) to Mpc860T for
my embedded system and OS is MVL PE3.0 in my board.
According to MPC860UM, Program the UPMs in the following steps:
1. Write patterns into the RAM array.
2. Program MPTPR
3. Program the machine mode register (MAMR and MBMR).
4. Set up BRx and ORx.

But I have a difficulty to write patterns into the RAM array because I
know little UPM timing. Who can give me a RAM table and MPTPR, MBMR example?

Thanks in advance!
