Notes for FIGURE 15 and associated table.
1. For the 16-bit buffered nonzero wait configuration, TRANSPA-
RENT/BUFFERED must be connected to logic "0". ZERO_WAIT
and DTREQ/16/8 must be connected to logic "1". The inputs TRIG-
GER_SEL and MSB/LSB may be connected to either +5 V or
ground.
2. SELECT and STRBD may be tied together. IOEN goes low on
the first rising CLK edge when SELECT
STRBD is sampled low
(satisfying t1) and the BU-65170/61580's protocol/memory manage-
ment logic is not accessing the internal RAM. When this occurs,
IOEN goes low, starting the transfer cycle. After IOEN goes low,
SELECT may be released high.
3. MEM/REG must be presented high for memory access, low for
register access.
4. MEM/REG and RD/WR are buffered transparently until the first
falling edge of CLK after IOEN goes low. After this CLK edge,
MEM/REG and RD/WR become latched internally.
5. The logic sense for RD/WR in the diagram assumes that POLAR-
ITY_SEL is connected to logic "1." If POLARITY_SEL is connected
to logic "0," RD/WR must be asserted low to read.
6. The timing for IOEN, READYD and D15-D0 assumes a 50 pf
load. For loading above 50 pf, the validity of IOEN, READYD, and
D15-D0 is delayed by an additional 0.14 ns/pf typ, 0.28 ns/pf max.
7. Timing for A15-A0, MEM/REG and SELECT assumes ADDR-LAT
is connected to logic "1." Refer to Address Latch timing for addition-
al details.
8. Internal RAM is accessed by A11 through A0 (A13 through A0 for
61585 and 61586). Registers are accessed by A4 through A0.
9. The address bus A15-A0 is internally buffered transparently until
the first rising edge of CLK after IOEN goes low. After this CLK
edge, A15-A0 become latched internally.
10. Setup time given for use in worst case timing calculations.
None of the ACE input signals are required to be synchronized to
the system clock. For ACE applications only, where SELECT and
STRBD do not meet the setup time of t1, but occur during the setup
window of an internal flip-flop, an additional clock cycle will be
inserted between the falling clock edge that latches MEM/REG and
RD/WR and the rising clock edge that latches the Address (A15-
A0). When this occurs, the pulse width of IOEN falling to READYD
falling (t11) increases by one clock cycle and the address hold time
(t10) must be increased be one clock cycle.
