Interrupts

 

INT *

 

 

Usage

 

 

 

 

 

 

/INT1, /INT2

 

 

IUSC logically or-ed interrupts. IUSC Interrupts can be muxed to any of the two INTs.

 

 

 

 

 

One use is to mux all ports configured for Async mode to one IRQ and all ports

 

 

 

 

 

configured for Sync mode to another interrupt. This should facilitate better software

 

 

 

 

 

architecture and operation.

 

 

/INT3

 

 

PLD Interrupt. To support miscellaneous PLD section functions.

 

 

/INT6

 

 

Ethernet PHY Interrupt. Same PHY as other MCF5272 based Blue Heat/Net models.

 

*INTs are active low. Unused interrupts are pulled up to V+.

Direction

 

 

Usage

 

 

 

 

 

 

 

PA0 – PA4,

 

 

Undefined

 

Undefined. For future expansion or debugging purposes. Available on

 

PA6

 

 

 

 

debug header P11 on page 8 of Schematic

 

PA5

 

 

Output

 

CPU Status LED.

 

 

 

 

 

 

 

1

= LED Off

 

 

 

 

 

 

 

0

= LED On.

 

PA8 – PA11

 

 

Input

 

PCB ID. Should be 0x4, for BHN Sync 4 Port.

 

PA13

 

 

Input

 

Pushbutton input.

 

 

 

 

 

 

 

1

= not pushed

 

 

 

 

 

 

 

0

= pushed

 

PA14

 

 

Output

 

Software forced hardware reset.

 

 

 

 

 

 

 

1

= Not reset. When setting up this GPIO, be sure to set port to a „1‟

 

 

 

 

 

 

 

before changing direction to output.

 

 

 

 

 

 

 

0

= forces a hardware reset

 

Table 7: ColdFire MCF5272 GPIO

* All unused GPIO is pulled up with a pullup resistor.
