Clock Input
Clock output at device speed
The CLK1EN bit in the EMIF GBLCTL register controls the CLKOUT1 pin.
CLK1EN = 0:
CLKOUT1 is disabled
CLK1EN = 1:
CLKOUT1 enabled to clock [default]
Clock output at half of device speed
When the CLKOUT2 pin is enabled, the CLK2EN bit in the EMIF global control register
(GBLCTL) controls the CLKOUT2 pin.
CLK2EN = 0:
CLKOUT2 is disabled
CLK2EN = 1:
CLKOUT1 enabled to clock [default]

RESETS AND INTERRUPTS
Device reset
Nonmaskable interrupt
Edge-driven (rising edge)
Any noise on the NMI pin may trigger an NMI interrupt; therefore, if the NMI pin is not used, it is
recommended that the NMI pin be grounded versus relying on the IPD.

I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground
IPD = Internal pulldown, IPU = Internal pullup. (These IPD/IPU signal pins feature a 30-k
IPD or IPU resistor. To pull up a signal to the opposite
supply rail, a 1-k
resistor should be used.)
