EMIF output clock depends on the EKSRC bit (DEVCFG.[4]) and on EKEN bit<br />

(GBLCTL.[5]).<br />

EKSRC = 0 – ECLKOUT is based on the internal SYSCLK3 signal<br />

from the clock generator (default).<br />

EKSRC = 1 – ECLKOUT is based on the the external EMIF input clock<br />

source pin (ECLKIN)<br />

EKEN = 0 – ECLKOUT held low<br />

EKEN = 1 – ECLKOUT enabled to clock (default)<br />

O/Z IPU starts with EA2 to maintain signal name compatibility with other C671x devices<br />

(e.g., C6711, C6713BGDP and C6713BZDP) [see the 32-bit EMIF addressing<br />

† I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal<br />

‡ IPD = Internal pulldown, IPU = Internal pullup. [To oppose the supply rail on these IPD/IPU signal pins, use external pullup or pulldown resistors<br />

no greater than 4.4 kΩ and 2.0 kΩ, respectively.]<br />

To maintain signal integrity for the EMIF signals, serial termination resistors should be inserted into all EMIF output signal lines.<br />
