Functional Description
The SPI flash part type is AT25DF321A-SH-T from Atmel. The AT25DF321A-SH-T supports SPI, and a high performance dual output SPI using four pins: serial clock, chipset select, serial data I/O, and serial data out. SPI clock frequencies of up to 33MHz are supported.
4.20Watchdog Timer
MITX-430/MITX-440-DVI-2E implements the watchdog timer feature. The SIO chipset is used to implement the watchdog function that supports 1-255s or 1-255m watchdog.
4.21Debug
MITX-430/MITX-440-DVI-2E implements three ways for debugging:
zVGA for text and graphic information output.
zRS232 for AMI debugger. It can set, modify, or check the breakpoint, register value, and so on.
zExtended Debug Port (XDP) tool for processor run control and debug.
4.22Power Management
MITX-430/MITX-440-DVI-2E supports ACPI S0, S3, S4, S5.
4.23Manageability
MITX-430/MITX-440-DVI-2E does not support AMT feature.
4.24RTC
MITX-430/MITX-440-DVI-2E supports a battery backed Real Time Clock (RTC). The ICH8 contains a Motorola MC146818A-compatible RTC with 256 bytes of battery backed RAM. The RTC performs two key functions: keeping track of the time of day and storing system data, even when the system is powered down. The RTC operates on a 32.768 KHz crystal and a 3V battery.
