HARDWARE INSTALLATION
This pin is reserved for manufacturing and debugging purposes.
May be used as JTAG_TDI signal for boundary scan purposes during
production. May also be used, via a multiplexer, as a UART_RX signal to
connect a simple UART for firmware and boot loader implementations. In
this case the multiplexer must be controlled by the MFG_NC4 signal.
This pin is reserved for manufacturing and debugging purposes.
May be used as JTAG_TMS signal for boundary scan purposes during
production. May also be used, via a multiplexer, as vendor specific BOOT
signal for firmware and boot loader implementations. In this case the
multiplexer must be controlled by the MFG_NC4 signal.
Or UART_RTS
This pin is reserved for manufacturing and debugging purposes.
May be used as JTAG_TRST# signal for boundary scan purposes during
production. May also be used as control signal for a multiplexer circuit on
the module enabling secondary function for MFG_NC0..3 ( JTAG / UART ).
Description
Thermal Alarm active low signal generated by the external hardware to
indicate an over temperature situation. This signal can be used to initiate
thermal throttling.
Thermal Trip indicates an overheating condition of the processor. If
'THRMTRIP#' goes active the system immediately transitions to the S5
State (Soft Off).
Description
Primary functionality is fan speed control. Uses the Pulse Width
Modulation (PWM) technique to control the Fan's RPM based on the
CPU's die temperature.
When not in use for this primary purpose it can be used as General
Purpose PWM Output.
Primary functionality is fan tachometer input. When not in use for this
primary purpose it can be used as General Purpose Timer Input.
Description
Power Supply +5VDC ±5%
Standby Power Supply +5VDC ±5%
3 V backup cell input. VCC_RTC should be connected to a 3V backup cell
for RTC operation and storage register non-volatility in the absence of
system power.
(VCC_RTC = 2.4 - 3.3 V).
