Figure 12.1. SFR Page Stack
Automatic hardware switching of the SFR Page on interrupts may be enabled or disabled as desired using
the SFR Automatic Page Control Enable Bit located in the SFR Page Control Register (SFR0CN). This
function defaults to “enabled” upon reset. In this way, the autoswitching function will be enabled unless dis-
abled in software.
A summary of the SFR locations (address and SFR page) are provided in Table 12.3 in the form of an SFR
memory map. Each memory location in the map has an SFR page row, denoting the page in which that
SFR resides. Certain SFRs are accessible from ALL SFR pages, and are denoted by the “(ALL PAGES)”
designation. For example, the Port I/O registers P0, P1, P2, and P3 all have the “(ALL PAGES)” designa-
tion, indicating these SFRs are accessible from all SFR pages regardless of the SFRPAGE register value.
