1.4. Operating Modes
The C8051F52x/F52xA/F53x/F53xA devices have four operating modes: Active (Normal), Idle, Suspend,
and Stop. Active mode occurs during normal operation when the oscillator and peripherals are active. Idle
mode halts the CPU while leaving the peripherals and internal clocks active. In Suspend and Stop mode,
the CPU is halted, all interrupts and timers are inactive, and the internal oscillator is stopped. The various
operating modes are described in Table 1.3 below:
Table 1.3. Operating Modes Summary
See Section “8.3. Power Management Modes” on page 89 for Idle and Stop mode details. See Section
“14.1.1. Internal Oscillator Suspend Mode” on page 135 for more information on Suspend mode.
