EMI signal descriptions
The following section describes the functions of the EMI pins. Note that a signal name prefixed by
not
indicates active low.
MemAddr1-19
External address bus. The ST20-GP1 uses 30 bits of addressing internally but only the bottom 18
bits are brought out to external pins (
MemAddr2-19
);
MemAddr1
is generated by the EMI.
MemAddr1-19
is valid and constant for the whole duration of an external access. The memory
locations in each bank can be accessed at multiple addresses, as bits 20-29 are ignored when
making external accesses.
MemData0-15
External data bus. The data bus may be configured to be either 8 or 16 bits wide on a per bank
basis.
MemData0
is always the least significant bit.
MemData7
is the most significant bit in 8-bit
mode and
MemData15
is the most significant bit in 16-bit mode. When performing a write access
to a bank configured to be 8-bits wide,
MemData8-15
are held in a high-impedance state for the
duration of the access;
MemData0-7
behave according to the configuration parameters as
specified in Section 9.5. When making a write to a bank configured to be 16-bits wide,
MemData0-15
behave according to the configuration parameters.
notMemCE0-3
Chip enable strobes, one per bank. The
notMemCE0-3
strobe corresponding to the bank being
accessed will be active on both reads and writes to that bank.
notMemOE3-0
Output enable strobes, one per bank. The
notMemOE0-3
strobe corresponding to the bank being
accessed will be active only on reads to that bank.
notMemWB0-1
Byte selector strobes to select bytes within a 16-bit half-word. These strobes are shared between
all four banks.
notMemWB0
always corresponds to write data on
MemData0-7
whether the bus is
currently 8 or 16 bits wide. When the EMI is writing to a bank configured to be 16 bits wide,
notMemWB1
corresponds to
MemData8-15
. When the EMI is accessing a bank configured to be
8 bits wide,
notMemWB1
becomes address bit 0 and follows the timing of
MemAddr1-19
for that
bank.
MemWait
Halt external access. The EMI samples
MemWait
at or just after the midpoint of an access. If
MemWait
is sampled high, the access is stalled.
MemWait
will then continue to be sampled and
the access proceeds when
MemWait
is sampled low. The action of
MemWait
may be disabled by
software, see Section 9.4. No mechanism is provided to abort an access; if
MemWait
is held high
too long the EMI will become a contentious resource and may stall the ST20-GP1.
BootSource0-1
These signals are sampled immediately after reset and determine both the bootstrap behavior and
