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: SFR Automatic Paging disabled. C8051 core will not automatically change to the appro-
priate SFR page (i.e., the SFR page that contains the SFRs for the peripheral/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 inter-
rupt.
SFR Page Bits: Byte Represents the SFR Page the C8051 MCU uses when reading or
modifying SFRs.
Write: Sets the SFR Page.
Read: Byte is the SFR page the C8051 MCU is using.
When enabled in the SFR Page Control Register (SFRPGCN), the C8051 will automatically
switch to the SFR Page that contains the SFRs of the corresponding peripheral/function that
caused the interrupt, and return to the previous SFR page upon return from interrupt (unless
SFR Stack was altered before a returning from the interrupt).
SFRPAGE is the top byte of the SFR Page Stack, and push/pop events of this stack are
caused by interrupts (and not by reading/writing to the SFRPAGE register)
