PINI/O (1)DESCRIPTION
NAMENO.
REFCLK_IN1I8Crystal Input: Reference clock crystal input(2) (3)
REFCLK_OL1O8Crystal Output: Reference clock crystal output(2)(5)
OCLKAAB24O14General Purpose Output Clock A (4)
Targeted for driving the Color Wheel motor controller. Frequency is software programmable, with a power-up default frequency of 0.99 MHz.
Note: the output frequency is not affected by non-power-up reset operations (that is, the system holds the last programmed value until the system is power cycled).
(1) See I/O Table for more information on I/O definitions.
(2) For more information on this signal, see System Oscillator Timing.
(3) For applications where an external oscillator is used in place of a crystal, use an oscillator to drive this pin.
(4) For more information on this signal, see Programmable Output Clock Timing.
(5) For applications where an external oscillator is used in place of a crystal, this pin should be grounded.
