Test chip SCC Registers 14, 16, 18, 22, 24 and 26 PLL value registers

The CFGREG11, CFGREG13, CFGREG15, and CFGREG17 Register characteristics are:

Purpose CFGREG14, CFGREG16, CFGREG18, CFGREG20, CFGREG22,

CFGREG24, and CFGREG26 are PLL value registers.

Together with the CFGREG15, CFGREG17, CFGREG19, CFGREG21,

CFGREG23, and CFGREG25 PLL control registers, they enable you to

read and write PLL configuration settings as follows:

• CFGREG13 and CFGREG14 control SYS PLL.

• CFGREG15 and CFGREG16 control DDR PLL.

• CFGREG17 and CFGREG18 control HDLCD PLL.

• CFGREG19 and CFGREG20 control A15 PLL 0.

• CFGREG21 and CFGREG22 control A15 PLL 1.

• CFGREG23 and CFGREG24 control A7 PLL 0.

• CFGREG25 and CFGREG26 control A7 PLL 1.

See Clocks on page 2-24.

Usage constraints There are no usage constraints.

Configurations Not applicable.

Attributes See Table 3-6 on page 3-13.

Figure 3-18 shows the bit assignments.
