71
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.

4.20 Watchdog 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.

4.21 Debug
MITX-430/MITX-440-DVI-2E implements three ways for debugging:
z
VGA for text and graphic information output.
z
RS232 for AMI debugger. It can set, modify, or check the breakpoint, register value, and so
on.
on.
z
Extended Debug Port (XDP) tool for processor run control and debug.
4.22 Power Management
MITX-430/MITX-440-DVI-2E supports ACPI S0, S3, S4, S5.
4.23 Manageability
MITX-430/MITX-440-DVI-2E does not support AMT feature.
4.24 RTC
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.
