TM4C129x of EPI Host-Bus 16

Other Parts Discussed in Thread: TM4C1290NCZAD

Hi, Everyone

I need your help.
We use TM4C1290NCZAD of EPI Host-Bus 16.
We consider TM4C129x and FPGA are connected with EPI Host-Bus 16.

Data sheet(SPMS430B) HB16 Signal (MODE=ADNOMUX (Cont.Read)) of Table 11-9 says
Address bus is until A11.
but Available Address of Table 11-7 says MAX Address bit is 28bit.

I understand like this about Table 11-9.

-HB16 Signal (MODE=ADNOMUX (Cont.Read)) ... MAX Address is 12bit
-HB16 Signal (MODE=ADMUX) ... MAX Address is 28bit

Is this understanding corect ?

Hello Hiroyasu,

The ADNOMUX has a MODE definition of 0x1. For this MODE value in HB16 the range is from 12-8 bits of address. The 12 bit is possible only when byte select are not used.

Hi, Amit

Thank you for your reply.
I wanna make sure ADMUX mode in HB16 MAX range is 28bit.

Hello Hiroyasu

Note that when ADMUX mode is used, there is an external latch (in this case the FPGA must ensure that it uses the ALE) to hold the address during the data phase

Hi,Amit

Thank you for your reply.

Actually We gonna use ADNOMUX mode.
I understand 8-12bit Address are used for ADNOMUX.
and We do not need to use 13-28bit.

I think these 13-28 bit are for ADMUX mode.
I wanna just know about this understanding is correct.

Hello Hiroyasu,

Which address lines are used based on the mode are defined in Table 11-9. If you can cross check against that it would be the right information.

Hi,Amit

Sorry.I made sure We are planning to use Address line 12bit on ADMUX.
We were resolve.Thank you !
