SFRPGEN SFR Automatic Page Control Enable.
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: Disable SFR automatic paging. The C8051 core will not automatically change to the
appropriate SFR page (i.e., the SFR page that contains the SFRs for the peripheral/func-
tion that was the source of the interrupt).
1: Enable SFR automatic paging. 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.
