C12
C12
Reserved (leave unconnected, do not connect to power or ground).
IPU Only the C6711/11B devices have internal pullup (IPU) on this pin.
On the C6711C device, this pin does not have an IPU.
RSV
D12
D12
Only the C6711/11B devices have internal pullups (IPUs). For the C6711/11B, the
D12 pin is reserved (leave unconnected, do not connect to power or ground).
IPU
On the C6711C device, this pin does not have an IPU. For proper C6711C device
operation, the D12 pin must be externally pulled down with a 10-kΩ resistor.

connected directly to CVDD (core power). For old designs, this can be left uncon-
nected.

† _{I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal (PLL Filter)}
‡ _{For C6711/11B, IPD = Internal pulldown, IPU = Internal pullup. (To pull up a signal to the opposite supply rail, a 1-kΩ resistor should be used.)}
For C6711C, 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.]
