/* Clocking
|
|
*
|
|
* The MakerLisp CPU board has a 5Mhz crystal. This is multiplied by 10 by
|
|
* the PLL to obtain a system clock frequency of 50MHz. See the PLL setup
|
|
* in scripts/makerlisp.linkcmd.

/* LEDs */
|

|
|
/* The D3 GREEN LED is driven by an eZ80 GPI/O pin. However, it has some
|
|
* additional properties:
|
|
*
|
|
* 1. On input, it will be '1' if the I/O expansion board is present.
|
|
* 2. Setting it to an output of '0' will generate a system reset.
|
|
* 3. Setting it to an output of '1' will not only illuminate the LED
|
|
* take the card out of reset and enable power to the SD card slot.
|
|
*
|
|
* As a consequence, the GREEN LED will not be illuminated if SD card
|
|
* support or SPI is disabled. The only effect of CONFIG_ARCH_LEDS is that
|
|
* the GREEN LED will turned off in the event of a crash.
