PIN I/O (1) DESCRIPTION
NAME NO.
REFCLK_I N1 I8

Clock

Input: Reference clock input. (2)(3)
REFCLK_O L1 O8

Clock

Output: Reference clock output.(2)(5)
OCLKA AB24 O14 General Purpose Output Clock A (4)
Frequency is software programmable, with a power-up default frequency of 0.99MHz.
Note: the output frequency is not affected by non-power-up reset operations (i.e., the system holds the last programmed value until 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 must be grounded.
