17.5 Mbits/second are possible at a CPU clock of 140 MHz. The QSPI supports master mode operation
only.
1.5.19
The MCF5253 incorporates two independent, general-purpose 16-bit timers. The output of an 8-bit
prescaler clocks each 16-bit timer. The prescaler input can be the system clock or the system clock divided
by 16. Timer0 output pin is multiplexed with SDATAO1/TOUT0/GPIO18. Upon reset, this pin is
programmed as SDATAO1. To use the TOUT0 pin function it is necessary to program the Pin
Configuration register appropriately.
1.5.20
The MCF5253 system bus allows connection of an IDE hard disk drive with a minimum of external
hardware. The external hardware consists of bus buffers for address and data and are intended to reduce
the load on the bus and prevent SDRAM and Flash accesses from propagating to the IDE bus. The control
signals for the buffers are generated in the MCF5253.
1.5.21
The six channel ADC is based on the Sigma-Delta concept with 12-bit resolution. Both the analog
comparator and digital sections are integrated in the MCF5253. An external integrator circuit
(resistor/capacitor) is required which is driven by the ADC output. A interrupt is provided when the ADC
measurement cycle is complete.

The two-wire I
serial bus that exchanges data between devices. The I
devices in the end system and is best suited for applications that need occasional bursts of rapid
communication over short distances among several devices. Bus capacitance and the number of unique
addresses limit the maximum communication length and the number of devices that can be connected.
1.5.24
There are three programmable chip selects on the MCF5253:
Freescale Semiconductor
•
Three programmable chip-select outputs (CS0/CS4, CS1 and CS2) provide signals that enable
glueless connection to external memory and peripheral circuits. The base address, access
permissions, and automatic wait-state insertion are programmable with configuration registers.
These signals also interface to 16-bit ports.
