Signal Descriptions
ENDIAN
40
I
Endian. Active high for big endian mode. Low for little endian mode
1 big endian
0 little endian
IRQ
85
O
Interrupt Request. Interrupt line that signies that one or more execution units
modules has asserted its IRQ hardware interrupt.
NC
26, 27, 49,
50, 51, 76,
100
—
No connection to the pin
DMA Hardware Handshake pins
DREQ1
83
O
DMA Request 1. Active high signal which indicates that either the input or output
buffer is requesting data transfer by the host or DMA controller. DREQ1 and
DREQ2 are each programmable to refer to the MPC180 chip input buffer or output
buffer. This signal is designed to interoperate with a PowerQUICC IDMA channel.
DREQ2
84
O
DMA request 2. Active high signal which indicates that either the input or output
buffer is requesting data transfer by the host or DMA controller. DREQ1 and
DREQ2 are each programmable to refer to the MPC180 Chip input buffer or output
buffer. This signal is designed to interoperate with a PowerQUICC IDMA channel.
