11.1. SFR Paging
To accommodate more than 128 SFRs in the 0x80 to 0xFF address space, SFR paging has been imple-
mented. By default, all SFR accesses target SFR Page 0x0 to allow access to the registers listed in
Table 11.1. During device initialization, some SFRs located on SFR Page 0xF may need to be accessed.
Table 11.2 lists the SFRs accessible from SFR Page 0x0F. Some SFRs are accessible from both pages,
including the SFRPAGE register. SFRs accessible only from Page 0xF are in bold.
The following procedure should be used when accessing SFRs from Page 0xF:
1. Save the current interrupt state (EA_save = EA).
2. Disable Interrupts (EA = 0).
3. Set SFRPAGE = 0xF.
4. Access the SFRs located on SFR Page 0xF.
5. Set SFRPAGE = 0x0.
6. Restore interrupt state (EA = EA_save).
