While CIP-51 executes in-line code (writing values to Port 5 in this example), ADC2 Window Comparator
Interrupt occurs. The CIP-51 vectors to the ADC2 Window Comparator ISR and pushes the current SFR
Page value (SFR Page 0x0F) into SFRNEXT in the SFR Page Stack. The SFR page needed to access
ADC2’s SFRs is then automatically placed in the SFRPAGE register (SFR Page 0x02). SFRPAGE is con-
sidered the “top” of the SFR Page Stack. Software can now access the ADC2 SFRs. Software may switch
to any SFR Page by writing a new value to the SFRPAGE register at any time during the ADC2 ISR to
access SFRs that are not on SFR Page 0x02. See Figure 13.5 below.
