This chapter describes the mechanical characteristics of the Diva module.

== Board Layout ==

== CAD Drawings ==

= Power, reset and control =

* PWRHOLD (input): This signal is connected to processor's PMIC_PWR_EN and is used to initiate power up sequence.

* PMIC_PWRON (input): A rising edge of this pin (automatically done at startup) the PMIC performs an OFF-to-ACTIVE state transition. On a falling edge of this pin, the PMIC performs an ACTIVE-to-OFF state transition. This signal is pulled-up to VIN through 10kOhm resistor.

== Reset scheme and voltage monitoring ==

== Boot Options ==

SYSBOOT[15:0] terminals are respectively LCD_DATA[15:0] inputs, latched on the rising edge of PWRONRSTn. The booting device list is created based on the SYSBOOT pins. A booting device can be a memory booting device (soldered flash memory or temporarily booting device like memory card) or a peripheral interface connected to a host. The main loop of the booting procedure goes through the booting device list and tries to search for an image from the currently selected booting device. This loop is exited if a valid booting image is found and successfully executed or upon watchdog expiration. The memory booting procedure is executed when the booting device type is one of NOR, NAND, MMC or SPI-EEPROM. The peripheral booting is executed when the booting device type is Ethernet, USB or UART.
