I agree with your guys, I have reported it.

nRF51 page size 256 words or 1024 bytes. nRF52 page size 1024 words or 4096 bytes. I also agree with you that here is error in the code. Instead i += sizeof(patwr); should be i += sizeof(addr);.

pg_size is given in bytes(i maybe mistaken) , not in words- because the addr is determined by (pg_size * pg_num)

i(in bytes) is compared to pg_size (words)

nRF51 and nRF52 SoC is built around a 32-bit ARM® Cortex. Cortex ARM is a 32 bit processor. 32 bit equal to one word. One word is 4 bytes. sizeof(patwr) equal to 1 byte. ++addr equal to ++4 bytes. (uint32_t)patwr equal to 4 bytes of data, just first 3 bytes will be 0. Word aligned mean that it should be 4 bytes data length and also should be word-aligned address.
