1.4.
The C8051F41x 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. Suspend mode halts SYSCLK until a waken-
ing event occurs, which also halts all peripherals using SYSCLK. In Stop mode, the CPU is halted, all inter-
rupts and timers are inactive, and the internal oscillator is stopped. The various operating modes are
described in Table 1.2 below:
