<Test conditions>
Notes 1: Operating in single-chip mode
Clock input from XIN pin (XOUT oscillator stopped)
USB operating with USB transceiver DC-DC converter enabled
Operating functions: Frequency synthesizer, CPU, two UARTs, DMAC, Timers and Count source generator
Disabled functions: Master CPU bus interface and Serial I/O
2: Operating in single-chip mode with Wait mode
Clock input from XIN pin (XOUT oscillator stopped)
USB suspended due to USB clock stopped with USB transceiver DC-DC converter enabled
Operating functions: Frequency synthesizer, Timers and Count source generator
Disabled functions: CPU, two UARTs, DMAC, Master CPU bus interface and Serial I/O
3: Operating in single-chip mode with Wait mode
XIN - XOUT oscillator stopped
Clock input from XCIN pin (XCOUT oscillator stopped)
USB stopped, USB clock stopped and USB transceiver DC-DC converter disabled
Operating functions: Timers and Count source generator
Disabled functions: Frequency synthesizer, CPU, two UARTs, DMAC, Master CPU bus interface and Serial I/O
