Register Descriptions
(continued)
PLL Control Register
Symbol: PLLC
Address: 20H
Bits: 6
The following PLL and memory controls are available through the PLL control register:
MEM5V
MEM5V is set to 1 when the memory supply is 5 volts. The default value of 0 is used when the
memory supply is 3.3 volts.
PLL5VA
PLL5VA is set to 1 when the phase-locked loop analog supply is 5 volts (default). A value of 0 is
used when the phase-locked loop analog supply is 3.3 volts.
PLL5VD
PLL5VD is set to 1 when the phase-locked loop digital supply is 5 volts. A value of 0 is used when
the phase-locked loop digital supply is 3.3 volts (default).
PLLS
PLLS controls the number of stages used in the PLL. When the PLL5VA is 1 (5V analog PLL
supply) PLLS should be 1, and seven stages are used. When PLL5VA is 0 (3.3V analog PLL
supply) PLLS should be 0, and five stages are used.
PLLCAP
PLLCAP controls the loop filter capacitor of the PLL. A recommended listing of PLLCAP vs.
Mode is shown below
PLLCPI
PLLCHI controls the charge pump current of the PLL. The default value should be used.
