Figure 10-8. Spurious Vector Register (SVR)
Table 10-13 describes the SVR fields.
10.3.2 Global Timer Registers
This section describes the global timer registers. Note that each of the four timers have four
individual configuration registers (GTCCRn, GTBCRn, GTVPRn, GTDRn), but they are only
shown once in this section.
10.3.2.1 Timer Frequency Reporting Register (TFRR)
The timer frequency reporting register (TFRR), shown in Figure 10-9, is written by software to
report the clocking frequency of the PIC timers. Note that although TFRR is read/write, the value
of this register is ignored by the PIC unit.
