Reading the appendix [2] I can decode the status register as follows:
0x80 = 01010000 the bits are SR4 and SR6
SR4 = Error in (page buffer) program or OTP program (PBPOPS)
SR6 = Block erase suspended (BESS)
I will try to disable /* #define
CMDSET0001_DISABLE_ERASE_SUSPEND_ON_WRITE */ and maybe #define
FORCE_WORD_WRITE 0
Thanks in advance for any help...
