RESERVED FOR TEST
RSV C12 IPU
Reserved (leave unconnected, do not connect to power or ground).
On this device, this pin does not have an IPU.
RSV D12 IPU
On this device, this pin does not have an IPU. For proper device operation, the D12 pin must
be externally pulled down with a 10-kΩ resistor.
RSV A5 IPU Reserved (leave unconnected, do not connect to power or ground)
RSV N2
Reserved. For proper device operation, this pin must be externally pulled up with a 10-kΩ
resistor.
RSV N1
Reserved. For proper device operation, this pin must be externally pulled up with a 10-kΩ
resistor.
RSV B5 Reserved (leave unconnected, do not connect to power or ground)
RSV D7 IPD Reserved (leave unconnected, do not connect to power or ground)
RSV A12
Reserved. [For new designs, it is recommended that this pin be connected directly to CV
DD
(core power). For old designs, this can be left unconnected.
RSV B11
Reserved [For new designs, it is recommended that this pin be connected directly to V
ss
(ground). For old designs, this pin can be left unconnected.

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 kΩ and 2.0 kΩ, respectively.]
