SFR page context is retained upon interrupts/return from interrupts in a 3 byte SFR Page
Stack: SFRPAGE is the first entry, SFRNEXT is the second, and SFRLAST is the third entry.
The SFR stack bytes may be used alter the context in the SFR Page Stack, and will not
cause the stack to ‘push’ or ‘pop’. Only interrupts and returns from the interrupt service rou-
tine push and pop the SFR Page Stack.
Write:
Sets the SFR Page in the last entry of the SFR Stack. This will cause the SFRNEXT SFR to
have this SFR page value upon a return from interrupt.
Read:
Returns the value of the SFR page contained in the last entry of the SFR stack.
