Upon interrupt, the C8051 Core will vector to the specified interrupt service routine
and automatically switch the SFR page to the corresponding peripheral or function’s
SFR page. This bit is used to control this autopaging function.
0: SFR Automatic Paging disabled. The C8051 core will not automatically change to
the appropriate SFR page (i.e., the SFR page that contains the SFRs for the periph-
eral/function that was the source of the interrupt).
1: SFR Automatic Paging enabled. Upon interrupt, the C8051 will switch the SFR
page to the page that contains the SFRs for the peripheral or function that is the
source of the interrupt.
