IRQ_STATUS Register of PN5180

[smiwa]

Hi Christian san,

According to its datasheet, the IRQ STATUS register is R/W type register. But I think it is actually read only register.

I tried to write to it by using phhalHw_Pn5180_Instr_WriteRegister()  but I got not changed value after writing and phhalHw_Pn5180_Instr_WriteRegisterOrMask() is as well.

Best regards,

Hi Christian san,

Sure, welcome!

And one more. As I have asked about Timer0 to Timer2 handler function by another thread, I found and guess that  they are no longer used for the application. Is this correct? 

Best regards,

Hi. Thanks for that information - you are right, IRQ_STATUS is a read/only register. To clear the IRQs IRQ_CLEAR register has to be used, for enabling/disabling register IRQ_ENABLE has to be used.

I will forward the information to the datasheet owner asking for a correction.
