376 EMBEDDED PROCESSOR
SINGLE-STEP TRAP
If the single-step flag (TF, bit 8) in the EFLAG regis-
ter is found to be set at the end of an instruction, a
single-step exception occurs. The single-step ex-
ception is auto vectored to exception number 1.
The Debug Registers are an advanced debugging
feature of the 80376. They allow data access break-
points as well as code execution breakpoints. Since
the breakpoints are indicated by on-chip registers,
an instruction execution breakpoint can be placed in
ROM code or in code shared by several tasks, nei-
ther of which can be supported by the INT 3 break-
point opcode.
The 80376 contains six Debug Registers, consisting
of four breakpoint address registers and two break-
point control registers. Initially after reset, break-
points are in the disabled state; therefore, no break-
points will occur unless the debug registers are
programmed. Breakpoints set up in the Debug
Registers
are
auto-vectored
Figure 2.6 shows the breakpoint status and control
registers.

3.0 ARCHITECTURE
The Intel 80376 Embedded Processor has a physi-
cal address space of 16 Mbytes (2
24
bytes) and al-
lows the running of virtual memory programs of al-
most unlimited size (16 Kbytes
c
16 Mbytes or
256 Gbytes (2
38
bytes)). In addition the 80376 pro-
vides a sophisticated memory management and a
hardware-assisted protection mechanism.
3.1 Addressing Mechanism
The 80376 uses two components to form the logical
address, a 16-bit selector which determines the lin-
ear base address of a segment, and a 32-bit effec-
tive address. The selector is used to specify an
index into an operating system defined table (see
Figure 3.1). The table contains the 32-bit base ad-
dress of a given segment. The linear address is
formed by adding the base address obtained from
the table to the 32-bit effective address. This value
is truncated to 24 bits to form the physical address,
which is then placed on the address bus.
