3.4.3 Address Bus
Address bus signals ADDR[23:0] define the address of the most significant byte to be transferred during
a bus cycle. The MCU places the address on the bus at the beginning of a bus cycle. The address is
valid while AS is asserted.
3.4.4 Address Strobe
AS is a timing signal that indicates the validity of an address on the address bus and the validity of many
control signals. It is asserted one-half clock after the beginning of a bus cycle.
3.4.5 Data Bus
Data bus signals DATA[15:0] make up a bidirectional, non-multiplexed parallel bus that transfers data
to or from the MCU. A read or write operation can transfer 8 or 16 bits of data in one bus cycle. During
a read cycle, the data is latched by the MCU on the last falling edge of the clock for that bus cycle. For
a write cycle, all 16 bits of the data bus are driven, regardless of the port width or operand size. The
MCU places the data on the data bus one-half clock cycle after AS is asserted in a write cycle.
3.4.6 Data Strobe
Data strobe (DS) is a timing signal. For a read cycle, the MCU asserts DS to signal an external device
to place data on the bus. DS is asserted at the same time as AS during a read cycle. For a write cycle,
DS signals an external device that data on the bus is valid. The MCU asserts DS one full clock cycle
after the assertion of AS during a write cycle.
3.4.7 Bus Cycle Termination Signals
During bus cycles, external devices assert the data transfer and size acknowledge signals (DSACK1
and DSACK0). During a read cycle, the signals tell the MCU to terminate the bus cycle and to latch data.
During a write cycle, the signals indicate that an external device has successfully stored data and that
the cycle can end. These signals also indicate to the MCU the size of the port for the bus cycle just com-
pleted. (Refer to 3.4.9 Dynamic Bus Sizing.)
The bus error (BERR) signal is also a bus cycle termination indicator and can be used in the absence
of DSACK1 and DSACK0 to indicate a bus error condition. It can also be asserted in conjunction with
these signals, provided it meets the appropriate timing requirements. The internal bus monitor can be
used to generate the BERR signal for internal and internal-to-external transfers. When BERR and HALT
are asserted simultaneously, the CPU takes a bus error exception.
Autovector signal (AVEC) can terminate external IRQ pin interrupt acknowledge cycles. AVEC indicates
that the MCU will internally generate a vector number to locate an interrupt handler routine. If it is con-
tinuously asserted, autovectors will be generated for all external interrupt requests. AVEC is ignored
during all other bus cycles.
