PN7462 Code Read/Write Protection Levels & IAP & ISP

Hi,

I have a question about code read/write protection levels and how they affect IAP and ISP.

If I set CWP_LEVEL to 1 by using 'phhalSysSer_Secrow_Config_t' can i continue to use 'phhalEeprom_WriteBuffer' and 'phhalFlash_WriteBuffer' functions to write data to flash & eeprom in my firmware.

If I set CRP_Level to 1 by using 'phhalSysSer_USB_Primary_Dnld_Config_t' can i continue to use 'phhalEeprom_Read' and 'phhalFlash_Read' functions to read data from flash & eeprom in my firmware.

Thanks.

I think it should can.

'phhalEeprom_WriteBuffer' 'phhalFlash_WriteBuffer‘ 'phhalEeprom_Read' and 'phhalFlash_Read' these fucntions are generic interface Hals.

CRP_Level and DRP_Level are for ROM interface Hals .

Daniel
