Typical cISD entry addresses and lengths

Entry point listed is offset from base cISD address (NOR:0x003F000 / NAND:0x0090800 in these examples)
Absolute start address is base cISD address + Entry point
Absolute end address is base cISD address + Entry point + Length

0x08	0x2	0x0100	Unknown
0x0A	0x6	0x00020133B2B6	CID aka Customer ID or Serial Number - varies per console (BL/Metldr per console keys + EID root keys calculated from this value on Sony's server) / Notice that the value in hex is actually in Ascii, so 00020133B2B6 / Can also be fetched at MMIO, sent by the config ring during POR / Similar to Fuse ID on PSP (Fuse ID is 6 bytes and a unique value in the Playstation Portable). Every refurfished consoles seems to have that value starting with 0x0FFF, versus 0x0001 or 0x0002 for virgin ones.
0x10	0x20	Ascii: 01CA0176410467180305494000000020	eCID (maybe official name is VisibleId, see PSVita NVS) - varies per console / Encrypted CID from above
0x30	0x8	Ascii: 27438416	board_id aka pd_label - part of console serial number. Note: not seen on the white serial sticker in all regions. Sample with (Europe) and without (USA). On prototypes it's in the format TS3XY... where X is the console type and Y the Chassis Type. This id is always the same if the same board is used, excluding retail  CEX  targets.

0x4C	0x4	0xFFFFFFFF	Likely padding
0x50	0x2	0x0001	CKP2 ManagementID - varies per console - semistatic see talkpage

Is just a "padding" to fit the whole size to 0x800 (2048 bytes)

cISD length is 0x270 (entire cISD area included header, file table, and all entries) + this padding 0x590 = 0x800
