For this device, the CLKOUT2 pin is multiplexed with the GP[2] pin.

 

 

 

 

 

 

Clock output at half of device speed (O/Z) [default] (SYSCLK2 internal signal from the clock

 

 

 

 

 

 

generator) or this pin can be programmed as GP[2] (I/O/Z).

When the CLKOUT2 pin is enabled, the CLK2EN bit in the EMIF global control register

 

 

 

 

 

 

 

 

 

 

(GBLCTL) controls the CLKOUT2 pin (All devices).

 

 

 

 

 

 

CLK2EN = 0: CLKOUT2 is disabled

 

 

 

 

 

 

CLK2EN = 1: CLKOUT2 enabled to clock [default]

I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal (PLL Filter)

IPD = Internal pulldown, IPU = Internal pullup. [To oppose the supply rail on these IPD/IPU signal pins, use external pullup or pulldown resistors no greater than 4.4 kand 2.0 k, respectively.]

§To ensure a proper logic level during reset when these pins are both routed out and 3−stated or not driven, it is recommended an external 10-k pullup/pulldown resistor be included to sustain the IPU/IPD, respectively.
