Clock Source
The TX19 core processor and peripherals operate at frequencies specified in the CG
block.
The processor and DMAC operations stop; other on-chip peripherals can be
selectively disabled.
Processor operation stops; the DMAC is operational; other on-chip peripherals can be
selectively disabled.
Processor operation stops; of the on-chip peripherals, only the RTC is operational (at
fs).
All processor and peripheral operations stop completely.
