Hello!
I have a question regarding how to set Reserved bits in the following registers
DCFG_CC_SOCU_NS_PIN (bits 14:10,
DCFG_CC_SOCU_NS_DFLT (bits 15:10, 8).
In User Manual, for SECURE_BOOT_CFG (page 153), PRINCE_BASE_ADDR (page 154) etc
it is specified that Reserved Bits should be filled with zeros.
Is that also mandatory for Reserved Bits in DCFG_CC_SOCU_NS_PIN, DCFG_CC_SOCU_NS_DFLT?
Thank you!
Solved! Go to Solution.
HI LucianA
If you don't want to enforce UUID checking, please leave these bits as default (0)
Hope this helps,

HI LucianA
To resolve your problem, please let me know,
- your chip part number
- document screenshot of where you concerned about.
Thanks for your cooperation,

Hi Jennie,
According to "LPC55S6x_LPC55S2x_LPC552x Protected Flash Region v1.3.xlsx"
DCFG_CC_SOCU_NS_PIN and DCFG_CC_SOCU_NS_DFLT registers have the same format for all those families.
However, I'm particularly interested for LPC5528 device.
It's a must to write zeros in the Reserved Bits marked in red in the attached picture (DCFG_CC_SOCU_NS_PIN[14:10] and DCFG_CC_SOCU_NS_PIN[8]) ?
Thank you!

Thanks Jennie,
I will keep all reserved bits on default values (zeros).
