noise immunity the PLL has its’ own power supply inputs: VDDPLL and VSSPLL. All other circuits are
powered by the normal supply pins, VDD and VSS.
1.2.22 Interrupt Controller (INTC0/INTC1)
There are two interrupt controllers on the MCF52235. These interrupt controllers are organized as seven
levels with up to nine interrupt sources per level. Each interrupt source has a unique interrupt vector, and
provide each peripheral with all necessary interrupts. Each internal interrupt has a programmable level
[1-7] and priority within the level. The seven external interrupts have fixed levels/priorities.
1.2.23 DMA Controller
The Direct Memory Access (DMA) Controller Module provides an efficient way to move blocks of data
with minimal processor interaction. The DMA module provides four channels (DMA0-DMA3) that allow
byte, word, longword or 16-byte burst line transfers. These transfers are triggered by software explicitly
setting a DCRn[START] bit or by the assertion of a DMA request from any number of on-chip peripherals.
The DMA controller supports dual address transfers to on-chip devices.
1.2.24 Reset
The reset controller determines the source of reset, asserts the appropriate reset signals to the system, and
keeps track of what caused the last reset. There are six sources of reset:
External reset input
Power-on reset (POR)
Watchdog timer
Phase locked-loop (PLL) loss of lock
PLL loss of clock
Software
Registers provide status flags indicating the last source of reset and a control bit for software assertion of
the RSTO pin.
1.2.25 GPIO
All of the pins associated with the external bus interface may be used for several different functions. When
not used this, all of the pins may be used as general-purpose digital I/O pins. In some cases, the pin function
is set by the operating mode, and the alternate pin functions are not supported.
The digital I/O pins on the MCF52235 are grouped into 8-bit ports. Some ports do not use all eight bits.
Each port has registers that configure, monitor, and control the port pins.
