Hello,
I have a hardware which utilizes a TL16C750 for additional UART functionality. TL16C750 is connected to the emif bus of my DM368 processor. I actually have two questions:
1. The hardware designer has connected E_A0..2 to A0..2 of TL16C750. E_BA0 and E_BA1 are not connected to anything. I have realized that my addresses are being asserted on 32 bit boundaries which makes Bank Addresses mentioned above a suspect. Is it possible to address 8 bit memory map devices using emif without having to use E_BA0 and E_BA1?
2. The ADS# (Address Strobe) provided to TL16C750 is always low. Does this device operate properly in this case? Does ADS# require to transition in order to be able to communicate? The data sheet says that while ADS# is low CS#, OE#, and WR are latched so it seems that it should work.
The problem that I have is even though i have perfect timing as far as CS#, OE#, adn WR# are concerned I cannot read or write form the device. Any ideas/
Regards,
