Table Address Register

This 32-bit read/write register points to a table of physical

addresses and byte counts that are used during DMA transfers

when table mode is selected. The table address must be longword

aligned because bits 0 and 1 are always zero. If the table address has

bit 0 or 1 set, they are truncated and no error is generated. These bits

are not affected by reset. Refer to Chapter 5 for details on Table

Address.Data Address Register

This 32-bit read/write register points to the physical address where

data is to be transferred. Data can only be transferred to/from

onboard DRAM or VMEbus memory. These bits are not affected by

resetByte Count Register

This 32-bit read/write register contains a 24-bit byte counter in bits

0-23, a 3-bit function code in bits 24-26, and a link bit in bit 31. The

byte counter contains the number of bytes to be transferred. The

function code bits are used when data is transferred. When set in a

table entry, the link bit indicates there are more entries in the DMA

table. This bit is cleared in the last table entry. The link bit is only

used in table mode and is never set by the MC68030. These bits are

not affected by reset.This 16-bit read/write register holds the tick timer preload value.

When the counter reaches $FFFF, it is loaded with this value and if

interrupts are enabled, an interrupt is generated. When running,

the counter is incremented every 6.25 microseconds. The following

equation should be used to determine the counter value (n) for a

periodic interrupt of time t where t is in seconds. The timer may be programmed to generate interrupts at intervals

between 6.25 microseconds and 0.4096 seconds. These bits are not

affected by reset.

Timer 1 Counter Register

This 16-bit read register is the output of the tick counter. Reads are

not synchronized with counter updates.Bit set and clear instructions should not be used on this

interrupt control register. Because an interrupt is

cleared by writing a 1 to the status bit and the status bit

is a 1 to indicate a pending interrupt, the read-modifywrite sequence may clear a pending interrupt.
