Bit 1

Bit 0

Name

OC8EN

OC7EN

OC6EN

OC5EN

OC4EN

OC3EN

OC2EN

OC1EN

Default

Bits 7 to 0: Output Clock x Enable (OCxEN). Each of these bits enables and disables the corresponding output

dividers, phase adjustment/alignment circuitry and start/stop circuitry. See section 5.6.1.

0 = Disabled

1 = Enabled

Note: On Rev A devices at least one OCxEN bit must be set for each of the six output banks for proper operation.

These bits should be set at or near the beginning of the configuration sequence.

Name

OCMUXC

OCMUXB

OCMUXA

Default

Bits 5 to 4: Output Clock Mux C (OCMUXC[1:0]). Controls the high speed output mux for output group C (OC4

and OC5).

00 = APLL1 Integer divider

01 = APLL1 Fractional divider or bypass path (specified by ACR1.BYPASS)

10 = APLL2 Integer divider

11 = APLL2 Fractional divider or bypass path (specified by A2CR1.BYPASS)

Bits 3 to 2: Output Clock Mux B (OCMUXB[1:0]). Controls the high speed output mux for output group B (OC3).

00 = APLL1 Integer divider

01 = APLL1 Fractional divider or bypass path (specified by ACR1.BYPASS)

10 = APLL2 Integer divider

11 = APLL2 Fractional divider or bypass path (specified by A2CR1.BYPASS)

Bits 1 to 0: Output Clock Mux A (OCMUXA[1:0]). Controls the high speed output mux for output group A (OC1

and OC2).

00 = APLL1 Integer divider

01 = APLL1 Fractional divider or bypass path (specified by ACR1.BYPASS)

10 = APLL2 Integer divider

11 = APLL2 Fractional divider or bypass path (specified by A2CR1.BYPASS)
