Modes of Operation
There are two main operating modes of PIT_RTI: run mode and stop mode. In run mode, PIT=0 in the
SIU_HLT register and all functional parts of the PIT_RTI module are running. In stop mode, PIT=1 in the
SIU_HLT register and all clocks to the PIT_RTI module are disabled except the XOSC.

Memory Map and Registers
This section provides a detailed description of all PIT_RTI registers.
28.3.1
Module Memory Map
The PIT_RTI memory map is shown in
. The address of each register is given as an offset to the
PIT_RTI base address. Registers are listed in address order, identified by complete name and mnemonic,
and lists the type of accesses allowed.
