Hi, communty,
A customer has some questions about i.MX6SDL EIM.
[Q1]
Please see the description of DSZ field in chapter 22.9.1 of IMX6SDLRM Rev.1.
It says "NOTE: Only async. access supported for 8 bit port.".
Customer is confused this expression.
Which is correct?
1. Async access can use only 8 bit port. (cannot use 16 bit port & 32 bit port)
2. Only async access can use 8 bit port. (sync access cannot use 8 bit port)
I guess 2. is correct, right?
[Q2]
Please see chapter 22.5.3.
It says "All modes are supported in with 8-, 16- or 32-bit port configuration, according to DSZ bit field".
But 8 bit port configuration is limited according to DSZ bit field.
Is this right?
Best Regards,
Satoshi Shimoda
Solved! Go to Solution.
Briefly :
1.
Correct, only async access can use 8 bit port (sync access cannot use 8 bit port).
2.
This is inaccuracy in Chapter 22.5.3, really "8 bit port configuration is limited" and
"sync access cannot use 8 bit port".
Have a great day,
Yuri
