4 Operating Modes and On-Chip Memory
4.1 Single-Chip Mode
In single-chip mode, ports B and C are available for general-purpose parallel I/O. Strobe pins A (STRA)
and B (STRB) can be used to control handshaking of parallel I/O on ports B and C. In this mode, all
software needed to control the MCU is contained in internal resources. ROM/EPROM (if present) will
always be enabled out of reset, ensuring that the reset and interrupt vectors will be available at locations
$FFC0–$FFFF.
4.2 Expanded Mode
In expanded operating mode, the MCU can access the full 64-Kbyte address space. The space includes
the same on-chip memory addresses used for single-chip mode as well as addresses for external pe-
ripherals and memory devices. The expansion bus is made up of ports B and C, and control signals AS
and R/W. R/W (read/write) and AS (address strobe) allow the low-order address and the 8-bit data bus
to be multiplexed on the same pins. During the first half of each bus cycle address information is
present. During the second half of each bus cycle the pins become the bidirectional data bus. AS is an
active-high latch enable signal for an external address latch. Address information is allowed through the
transparent latch while AS is high and is latched when AS drives low. Figure 5 shows an example of
address and data demultiplexing.
