The shutdown proceeds without verifying that each signal is de-asserted in the correctsequence.Wakeup EventsThe following wake-up sources are available for waking up the system from the S3 state: Power Button Wake on LAN signal (WOL) WAKE0# (Pin B66) PCI Express wake up signal WAKE1# (Pin B67) General purpose wake up signalThe following wake-up sources are available for waking up the system from the S5 and S4 state:Power ButtonRamping up of main power or standby voltage in combination with a compatible boot modesetting (see section 6.5.1).Toradex AG l Altsagenstrasse 5 l 6048 Horw l Switzerland l +41 41 500 48 00 l www.toradex.com l info@toradex.com Page | 32
Robin Z5xx Datasheet6. Robin Embedded ControllerThe embedded controller on the Robin computer module is a PSoC CY8C24794 from Cypress. ThePSoC is a powerful 8 bit microcontroller with USB interface and analog user blocks. The keyresponsibilities of the embedded controller are to provide the power management, watchdogfunctionality, user GPIO system and I2C interface.The firmware used in the Robin Embedded Controller is compatible with the Toradex Oak Sensorfamily. For core functionality, the same software libraries can be used. The embedded controllerappears in the operating system as standard USB Human Interface Device (HID). Therefore, for allmajor operating systems, no additional drivers are necessary. The communication protocolimplemented in the embedded controller makes use of three different report modes. The INTERRUPTOUT report mode is used to control the GPIO ports of the embedded controller and to service thewatchdog in real time with a maximum latency of 1ms. The INTERRUPT IN report mode allows theembedded controller to transmit real time data relating to GPIO status and I2C bus data back to themain processor. The FEATURE report mode is independent from the interrupt scheduled reportmodes and is used as bidirectional non-real time communication channel for configuring powermanagement, watchdog and GPIO settings.6.1. INTERRUPT OUT Report Contents (Real time data)The interrupt out report contains two commands for switching the 8 I/O channels, watchdog servicinginformation and I 2 C commands.Byte Position Size [Bit] Name Function0 8 OUT1CMD Command 1 for I/O port bit[7..0]1 8 OUT2CMD Command 2 for I/O port bit[7..0]2 8 WDS Watchdog serving3 8 I2C_ID Number to identify the I 2 C message4 8 I2C_CMD Command for the I 2 C Interface5 8 I2C_ADDR Slave Address for I 2 C command6 8 I2C_COUNT Number of Bytes to send/receive (I 2 C)7...115 x 8 I2C_DATA_OUT0 …I2C_DATA_OUT4I2C Data to send (payload 5 bytes)Toradex AG l Altsagenstrasse 5 l 6048 Horw l Switzerland l +41 41 500 48 00 l www.toradex.com l info@toradex.com Page | 33
