MC9S08AC60 will not load data from EEPROM

[wtyler]

I am currently using a MC9S08AC60 to control a Key Pad and display. The problem is after a while the Micro will not load the the 4KB EEPROM graphics data to the display after a KBI1P4/PTG4 is triggered.

can you please give me more information about the problem

are you using an external eeprom? 

are you using SPI or IIC to load the data on the EEPROM?

Can you please give me more information about the problem: After the micro processes an IRQ there is no MOSI/MISO data activity.

Are you using an external EEPROM: Yes after the Micro IRQ the data from the Micro is loaded to the EEPROM through a level shifter to a graphic display. Problem is the graphic data is not displayed from the Micro.

Are you using SPI or llC to load the data on the EEPROM: I Sam using SPI MOSI/MISO to load the EEPROM

Can you check if the data is sending properly on the SPI to the EEPROM?

Do you have any flag pending?

have a good day

After the IRQ no data is sent to the EEPROM. I don’t know how to check the flags.
