Select this if you want to use prioritized IRQ handling.
|
|
This feature prevents higher priority ISR to be interrupted
|
|
by lower priority IRQ even IRQF_DISABLED flag is not set.
|
|
This may be useful in embedded applications, where are strong
|
|
requirements for timing.
|
|
Say N here, unless you have a specialized requirement.

help
|
|
The debug board is an integral part of the MXC 3-stack(PDK)
|
|
platforms, it can be attached or removed from the peripheral
|
|
board. On debug board, several debug devices(ethernet, UART,
|
|
buttons, LEDs and JTAG) are implemented. Between the MCU and
|
|
these devices, a CPLD is added as a bridge which performs
|
|
data/address de-multiplexing and decode, signal level shift,
|
|
interrupt control and various board functions.

Use EPIT as the system timer on systems that have it. Normally you
|
|
don't have a reason to do so as the EPIT has the same features and
|
|
uses the same clocks as the GPT. Anyway, on some systems the GPT
|
|
may be in use for other purposes.
