80C51 with 512 B/1 kB/2 kB RAM, dual I2C-bus, SPI

6.13.1 Idle mode

Idle mode is entered setting the IDL bit in the PCON register. In Idle mode, the program

counter is stopped. The system clock continues to run and all interrupts and peripherals

remain active. The on-chip RAM and the special function registers hold their data during

this mode.

The device exits Idle mode through either a system interrupt or a hardware reset. Exiting

Idle mode via system interrupt, the start of the interrupt clears the IDL bit and exits Idle

mode. After exit the Interrupt Service Routine, the interrupted program resumes execution

beginning at the instruction immediately following the instruction which invoked the Idle

mode. A hardware reset starts the device similar to a power-on reset.

6.13.2 Power-down mode

The Power-down mode is entered by setting the PD bit in the PCON register. In the

Power-down mode, the clock is stopped and external interrupts are active for level

sensitive interrupts only. SRAM contents are retained during Power-down, the minimum

VDD level is 2.0 V.

The device exits Power-down mode through either an enabled external level sensitive

interrupt or a hardware reset. The start of the interrupt clears the PD bit and exits

Power-down. Holding the external interrupt pin low restarts the oscillator, the signal must

hold low at least 1024 clock cycles before bringing back high to complete the exit. Upon

interrupt signal restored to logic VIH, the interrupt service routine program execution

resumes beginning at the instruction immediately following the instruction which invoked

Power-down mode. A hardware reset starts the device similar to power-on reset.

To exit properly out of Power-down, the reset or external interrupt should not be executed

before the VDD line is restored to its normal operating voltage. Be sure to hold VDD voltage

long enough at its normal operating level for the oscillator to restart and stabilize (normally

less than 10 ms).
