FUNCTIONAL DESCRIPTION
The Am186ER and Am188ER microcontrollers are
based on the architecture of the original Am186 and
Am188 microcontrollers and they function in the en-
hanced mode of the Am186 and Am188 microcontrol-
lers. Enhanced mode includes system features such as
power-save control.
Each of the 8086, 8088, 80186, and 80188 microcon-
trollers contains the same basic set of registers, in-
structions, and addressing modes. The Am186ER and
Am188ER microcontrollers are backward compatible
with the 80C186/80C188 and Am186/Am188 micro-
controllers.
A full description of the Am186ER and Am188ER mi-
crocontrollers’ registers and instructions is included in
the Am186ER and Am188ER Microcontrollers User’s
Manual
, order #21684.
Memory Organization
Memory is organized in sets of segments. Each seg-
ment is a linear contiguous sequence of 64K (2
16
) 8-bit
bytes. Memory is addressed using a two-component
address consisting of a 16-bit segment value and a 16-
bit offset. The 16-bit segment values are contained in
one of four internal segment registers (CS, DS, SS, or
ES). The physical address is calculated by shifting the
segment value left by 4 bits and adding the 16-bit offset
value to yield a 20-bit physical address (see Figure 3).
This allows for a 1-Mbyte physical address size.
All instructions that address operands in memory must
specify the segment value and the 16-bit offset value.
For speed and compact instruction encoding, the seg-
ment register used for physical address generation is
implied by the addressing mode used (see Table 7).
Figure 3.
Two-Component Address Example
I/O Space
The I/O space consists of 64K 8-bit or 32K 16-bit ports.
Separate instructions (IN, INS and OUT, OUTS)
address the I/O space with either an 8-bit port address
specified in the instruction, or a 16-bit port address in
the DX register. Eight-bit port addresses are zero-
extended such that A15–A8 are Low.
