Overview
1.1.8
The SDRAM controller provides all required signals for glueless interfacing to a variety of
JEDEC-compliant SDRAM devices. SRAS/SCAS address multiplexing is software configurable for
different page sizes. To maintain refresh capability without conflicting with concurrent accesses on the
address and data buses, SRAS, SCAS, DRAMW, SDRAM_CS[1:0], and SCKE are dedicated SDRAM
signals.
1.1.9
The MCF5282 supports circuit board test strategies based on the Test Technology Committee of IEEE and
the Joint Test Action Group (JTAG). The test logic includes a test access port (TAP) consisting of a 16-state
controller, an instruction register, and three test registers (a 1-bit bypass register, a 256-bit boundary-scan
register, and a 32-bit ID register). The boundary scan register links the device’s pins into one shift register.
Test logic, implemented using static logic design, is independent of the device system logic.
The MCF5282 implementation supports the following:
1.1.10
The MCF5282 contains three full-duplex UARTs that function independently. The three UARTs can be
clocked by the system clock, eliminating the need for an external crystal.
Each UART has the following features:

Perform boundary-scan operations to test circuit board electrical continuity
Sample MCF5282 system pins during operation and transparently shift out the result in the
boundary scan register
Bypass the MCF5282 for a given circuit board test by effectively reducing the boundary-scan
register to a single bit
Disable the output drive to pins during circuit-board testing
Drive output pins to stable levels
Each can be clocked by the system clock, eliminating a need for an external UART clock
Full-duplex asynchronous/synchronous receiver/transmitter channel
Quadruple-buffered receiver
Double-buffered transmitter
Independently programmable receiver and transmitter clock sources
Programmable data format:
— 5–8 data bits plus parity
— Odd, even, no parity, or force parity
— One, one-and-a-half, or two stop bits
Each channel programmable to normal (full-duplex), automatic echo, local loop-back, or remote
loop-back mode
Automatic wake-up mode for multidrop applications
Four maskable interrupt conditions
All three UARTs have DMA request capability
Parity, framing, and overrun error detection
False-start bit detection
Line-break detection and generation
