PLL Operation
7.1.1 PLL:PCLK Ratios
The specifications for the clocks in the PLL module are summarized in Table 0-1.
7.2 PLL Operation
The following sections provide detailed information about the three PLL modes.
7.2.1 Reset/Initialization
The PLL receives RSTI as an input directly from the pin. Additionally, signals are
multiplexed with D[3:0]/FREQ[1:0]:DIVIDE[1:0] while RSTI is asserted. These signals
are sampled during reset and registered by the PLL on the negation of RSTI to provide
initialization information. FREQ[1:0] and DIVIDE[1:0] are used by the PLL to select the
CLKIN frequency range and set the CLKIN/PCLK ratio, respectively.
7.2.2 Normal Mode
PCLK is divided to create the system bus clock, BCLKO. At reset, the logic level of
DIVIDE[1:0]/D[1:0] determines the BCLKO divisor. The bus clock can be 1/2, 1/3, or 1/4
of the PCLK frequency.
7.2.3 Reduced-Power Mode
The PCLK can be turned off in a predictable manner to conserve system power. To allow
fast restart of the MCF5307 processor core, the PLL continues to operate at the frequency
configured at reset. PCLK is disabled using the CPU STOP instruction and resumes normal
operation on interrupt, as described in Section 7.2.4, “PLL Control Register (PLLCR).”
