MCF547x Integrated Microprocessor Hardware Specifications
MOTOROLA
PRELIMINARY—SUBJECT TO CHANGE WITHOUT NOTICE
Signal Description
1.5.1.5.1
Reset In (RSTI)
Asserting RSTI causes the MCF547x to enter reset exception processing. RSTO is asserted automatically
when RSTI is asserted.
1.5.1.5.2
Reset Out (RSTO)
After RSTI is asserted, the PLL temporarily loses its lock, during which time RSTO is asserted. When the
PLL regains its lock, RSTO negates again. This signal can be used to reset external devices.
1.5.1.5.3
Clock In (CLKIN)
CLKIN is the MCF547x input clock frequency to the on-board phase-locked loop (PLL) clock generator.
CLKIN is used to internally clock or sequence the MCF547x internal bus interface at a selected multiple of
the input frequency used for internal module logic. CLKIN is used as the clock reference for PCI and
FlexBus transfers.
1.5.1.6
Reset Configuration Pins
This section describes address/data pins, AD[12:0], that are read at reset to configure the MCF547x.
1.5.1.6.1
AD[12:8] / CLKIN to SDCLK Ratio (CLKCONFIG[4:0])
The clock configuration inputs, CLKCONFIG[4:0], indicate the CLKIN to SDCLK ratio. CLKIN is used
as the external reference for both PCI and FlexBus cycles. The CLKIN to SDCLK ratio is selectable, where
SDCLK is the clock frequency used for SDRAM accesses and the internal XLB bus. The core is always
clocked at twice the SDCLK frequency.
These signals are sampled on the rising edge of RSTI. Table 6 shows how the logic levels of AD[12:8]
correspond to the selected clock ratio.
1.5.1.6.2
AD5—FlexBus Size Configuration (FBSIZE)
At reset, the enabling and disabling of BE/BWE[3:0] versus TSIZ[1:0] and ADDR[1:0] is determined by
the logic level driven on AD5 at the rising edge of RSTI. FBSIZE is multiplexed with AD5 and sampled
only at reset. Table 7 shows how the AD5 logic level corresponds to the BE/BWE[3:0] function.
