Manual says they should be found in the datasheet but so far I have been unable to find the lock/unlock values for the AXI and AHB MPUs. Does anybody know them?

Hi,
You can find the required registers in document https://www.cypress.com/file/300921/download in the below sections.
CHAPTER 26: Memory Protection Unit for AXI of SHE
4.10. MPU AXI Unlock Register (MPUXSHE_UNLOCK)
CHAPTER 29: MPU16 AHB
2.8. MPU16 AHB Unlock Register (MPUHn_UNLOCK)
The unlock and lock values for MPUXSHE_UNLOCK are same as that of MPUHn_UNLOCK.
Regards,
Nambi
