22 / 66 page  STw8009/STw8019 Functional description 21/65 4.13.2 Mode transition diagram The following mode transition diagram shows the main possible transitions between the modes and the actions. Figure 17. Mode transition diagram Transitions to OFF mode The possible transitions are indicated in Figure 17: Mode transition diagram10 in dotted lines. No internal data needs to be saved and the STw80x9 can be turned OFF from any mode. The only restriction is to comply with the power supply rules described here after. Transition from OFF mode to Sleep mode then to Active mode Power up must be done by starting from OFF to Sleep mode and then from Sleep to Active mode. Sleep to Standby is not possible. The host sends the order for the STw80x9 to switch from Sleep to Active mode by releasing Suspend ball. The device then generates a reset sequence to the DENC part. Transition from Active mode to Sleep mode In Sleep mode, DENC is not powered on. When Suspend signal changes from « 0 » to « 1 », the device goes from Active to Sleep mode and an internal Reset signal is generated by the Control Power Unit management to the DENC part. This signal has a 6 pixclk duration (pixclk = 27 MHz). OFF Sleep Standby Active Registers maintained Power consumption reduced DENC clock gated DACs in low power Normal operation All functions available DACs dynamically used on demand No Power supply applied Registers values lost All supplies are applied but STw8009 suspend is asserted Register values lost DAC in low power mode STw8009 looses all its registers and configuration when entering Sleep mode A PORn reset occurs after the 1.2 V & 1.8 V have been applied No need to reset or reconfigure DENC in either direction Suspend = « 0 » By Sw Suspend = « 1 » OFF Sleep Standby Active Registers maintained Power consumption reduced DENC clock gated DACs in low power Normal operation All functions available DACs dynamically used on demand No Power supply applied Registers values lost All supplies are applied but STw8009 suspend is asserted Register values lost DAC in low power mode STw8009 looses all its registers and configuration when entering Sleep mode STw8009 looses all its registers and configuration when entering Sleep mode A PORn reset occurs after the 1.2 V & 1.8 V have been applied No need to reset or reconfigure DENC in either direction No need to reset or reconfigure DENC in either direction Suspend = « 0 » By Sw Suspend = « 1 » A PORn reset occurs after the 1.2V, 1.8V and CLK27M have been applied (see AN2347). |
