SFR Page Bits.
This is the value that will go to the SFR Page register upon a return from inter-
rupt.
Write: Sets the SFR Page contained in the second byte of the SFR Stack. This
will cause the SFRPAGE SFR to have this SFR page value upon a return from
interrupt.
Read: Returns the value of the SFR page contained in the second byte of the
SFR stack.
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 return from interrupts cause pushes and pops of the SFR Page
Stack.
