Hey hi , I am very confused between this two file. Currently I am working with SAMD21 controller based on Cortex M0+ processor so on referring this two file , i found variations.
while dealing with system exception in "System Control Block" the two manuals shows as:
Cortex-M0+Revision: r0p1Technical Reference Manual : According to this it has "System Handler Control and State Register"
Cortex-M0+ DevicesGeneric User Guide : Acording to this there is no such register.
Whereas in Controller startup file , I found the SHCSR register.
So kindly please tell me both manual are for what.
I think the problem is the "generic" in the user guide. The Armv6-M manual states that the SHCSR register is optional in case the debug extension is implemented.
