Table 3.3.6 Circuit Block Operating Status in Each Mode
The TX19 processor core and peripheral I/O both operate at the maximum frequency.
The TX19 processor core, INTC, timer for real-time clock, WDT, 2-phase pulse input counter,
KWUP (dynamic pull-up), PIO, and EBIF operate with the low-speed clock.
Processor operation stops and peripheral I/O operates as specified.
Processor operation stops. Only the internal low-speed oscillator, timer for real-time clock,
2-phase pulse input counter, and KWUP (dynamic pull-up) operate (fs).
Processor and peripheral I/O operation stops completely.
