DESCRIPTION
CLOCK GENERATOR
IPD
DV_DD33
This pin is multiplexed between the System Clock generator (PLL1), PWM2,
and GPIO.
For the System Clock generator (PLL1), it is clock output CLKOUT0. This is
configurable for 27 MHz or other 27 MHz-divided-down (/1 to /32) clock
outputs.
(1) I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal
(2) IPD = Internal pulldown, IPU = Internal pullup. For more detailed information on pullup/pulldown resistors and situations where external
pullup/pulldown resistors are required, see Section 3.9.1, Pullup/Pulldown Resistors.
(3) Specifies the operating I/O supply voltage for each signal
