Regarding Synergy S5 IAP programming

Hello,

I am working on Synergy S5 flash programming for bootloader application.

I am using IAR workbench. Regarding flash programming I couldn't find the enough information about flash programming registers and functional information in user manual ( r01um0004eu0100-synergy-s5d9.pdf ). 

I have code for flash writing from SSP.

When I debug following condition is fails in "FlashWrite" function.

if (0UL != R_FACI->FASTAT_b.CMDLK)    // Check if there were any errors

Could you please give me a pointer to resolve this.

Thanks,

Ganesh
