A complete description of the protocol and AC tim-
ing characteristics can be found in the CL-PS6700
data sheet. A transaction is initiated by an access to
the nCS4 or nCS5 area. The chip select is asserted,
and on the first clock, the upper 10 bits of the PC
Card address, along with 6 bits of size, space, and
slot information are put out onto the lower 16 bits
of the EP7212’s data bus. Only word (i.e., 4-byte)
and single-byte accesses are supported, and the slot
field is hardcoded to 11, since the slot field is de-
fined as a ‘Reserved field’ by the CL-PS6700. The
chip selects are used to select the device to be ac-
cessed. The space field is made directly from the
A26 and A27 CPU address bits, according to the
decode shown in
Table 18
. The size field is forced
to 11 if a word access is required, or to 00 if a byte
access is required. This avoids the need to config-
ure the interface after a reset. On the second clock
cycle, the remaining 16 bits of the PC Card address
are multiplexed out onto the lower 16 bits of the
data bus. If the transaction selected is a CL-PS6700
register transaction, or a write to the PC Card (as-
suming there is space available in the CL-PS6700’s
internal write buffer) then the access will continue
on the following two clock cycles. During these
following two clock cycles the upper and lower
halves of the word to be read or written will be put
onto the lower 16 bits of the main data bus.
The ‘ptype’ signal on the CL-PS6700s should be
connected to the EP7212’s WRITE output pin.
During PC Card accesses, the polarity of this pin
changes, and it becomes low to signify a write and
high to signify a read. It is valid with the first half
word of the address. During the second half word
of the address, it is always forced high to indicate
to the CL-PS6700 that the EP7212 has initiated ei-
ther the write or read.
The PRDY signals from each of the two CL-
PS6700 devices are connected to Port B bits 0 and
1, respectively. When the PC CARD1 or PC
CARD2 control bits in the SYSCON2 register are
de-asserted, these port bits are available for GPIO.
When asserted, these port bits are used as the
Access Type
