ColdFire Module Description
2
short distances among several devices. The I
C can operate in master, slave, or
multiple-master modes.
1.3.7 System Interface
The MCF5307 processor provides a direct interface to 8-, 16-, and 32-bit FLASH, SRAM,
ROM, and peripheral devices through the use of fully programmable chip selects and write
enables. Support for burst ROMs is also included. Through the on-chip PLL, users can
input a slower clock (16.6 to 45 MHz) that is internally multiplied to create the faster
processor clock (33.3 to 90 MHz).
1.3.7.1 External Bus Interface
The bus interface controller transfers information between the ColdFire core or DMA and
memory, peripherals, or other devices on the external bus. The external bus interface
provides up to 32 bits of address bus space, a 32-bit data bus, and all associated control
signals. This interface implements an extended synchronous protocol that supports bursting
operations.
Simple two-wire request/acknowledge bus arbitration between the MCF5307 processor
and another bus master, such as an external DMA device, is glueless with arbitration logic
internal to the MCF5307 processor. Multiple-master arbitration is also available with some
simple external arbitration logic.
1.3.7.2 Chip Selects
Eight fully programmable chip select outputs support the use of external memory and
peripheral circuits with user-defined wait-state insertion. These signals interface to 8-, 16-,
or 32-bit ports. The base address, access permissions, and internal bus transfer terminations
are programmable with configuration registers for each chip select. CS0 also provides
global chip select functionality of boot ROM upon reset for initializing the MCF5307.
1.3.7.3 16-Bit Parallel Port Interface
A 16-bit general-purpose programmable parallel port serves as either an input or an output
on a pin-by-pin basis.
1.3.7.4 Interrupt Controller
The interrupt controller provides user-programmable control of ten internal peripheral
interrupts and implements four external fixed interrupt-request pins. Each internal interrupt
can be programmed to any one of seven interrupt levels and four priority levels within each
of these levels. Additionally, the external interrupt request pins can be mapped to levels 1,
3, 5, and 7 or levels 2, 4, 6, and 7. Autovector capability is available for both internal and
external interrupts.
