EM6580

2. Operating modes

The EM6580 can operate in three different modes of which 2 are low-power dissipation modes (Stand-By and

Sleep). The modes and transitions between them are shown in Figure 5.

1.) Active mode

2.) Stand-By mode

3.) Sleep mode

2.1 ACTIVE Mode

The active mode is the actual CPU running mode. Instructions are read from the internal ROM and executed by

the CPU. Leaving the active mode: via the halt instruction to go into standby mode, writing the SLEEP bit to go

into Sleep mode or detecting the reset to go into reset mode.

2.2 STANDBY (Halt) Mode

Executing a HALT instruction puts the EM6580 into standby mode. The voltage regulator, oscillator, watchdog

timer, interrupts, timers and counters are operating. However, the CPU stops since the clock related to

instruction execution stops. Registers, RAM and I/O pins retain their states prior to STANDBY mode.

STANDBY is cancelled by a RESET or an Interrupt request if enabled.

2.3 SLEEP Mode

Writing to the Sleep bit in the RegSysCntl1 register puts the EM6580 in sleep mode. The oscillator stops and

most functions of the EM6580 are inactive. To be able to write to the Sleep bit, the SleepEn bit in

RegSysCntl2 must first be set to "1". In SLEEP mode only the voltage regulator is active to maintain the RAM

data integrity, the peripheral functions are stopped and the CPU is reset.all other functions are in reset state.

SLEEP mode may be cancelled by Wake/Up on change, external reset or by Sleep Reset Counter if any of

them is enabled.

Waking up from sleep mode may takes some time to guarantee stable oscillation. Coming back from sleep

mode puts the EM6681 in reset state and as such reinitializes all registers to their reset value. During sleep

mode and the following start up the EM6580 is in reset state. Waking up from sleep mode clears the Sleep flag

but not the SleepEn bit. Inspecting the SleepEn allows to determine if the EM6580 was powered up (SleepEn

= "0") or woken from sleep mode (SleepEn = "1").
