Note: EMIFA address numbering for the C6412 device starts with AEA3 to maintain
signal name compatibility with other C64x
devices (e.g., C6414, C6415, and C6416)
[see the 64-bit EMIF addressing scheme in the

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.)
§These pins are multiplexed pins. For more details, see the Device Configurations section of this data sheet.
PLLV is not part of external voltage supply. See the Clock PLL section for information on how to connect this pin.
#A = Analog signal (PLL Filter)
||The EMU0 and EMU1 pins are internally pulled up with 30-k
resistors; therefore, for emulation and normal operation, no external
pullup/pulldown resistors are necessary. However, for boundary scan operation, pull down the EMU1 and EMU0 pins with a dedicated 1-k
resistor.
