can be latched with the BUSY rising edge. Mode 1a shows
operation with a narrow logic low CONVST pulse. Mode 1b
shows a narrow logic high CONVST pulse.
In mode 2 (Figure 18) CS is tied low. The falling edge of
CONVST signal again starts the conversion. Data outputs
are in three-state until read by the MPU with the RD signal.
Mode 2 can be used for operation with a shared MPU
databus.
In slow memory and ROM modes (Figures 19 and 20) CS
is tied low and CONVST and RD are tied together. The MPU
starts the conversion and reads the output with the RD
signal. Conversions are started by the MPU or DSP (no
external sample clock).
In slow memory mode the processor applies a logic low to
RD (= CONVST) starting the conversion. BUSY goes low
forcing the processor into a WAIT state. The previous
conversion result appears on the data outputs. When the
conversion is complete, the new conversion results ap-
pear on the data outputs; BUSY goes high releasing the
processor, and the processor takes RD (= CONVST) back
high and reads the new conversion data.
In ROM mode, the processor takes RD (= CONVST) low,
starting a conversion and reading the previous conversion
result. After the conversion is complete, the processor can
read the new result and initiate another conversion.
