rising edge of SCLK after
CS
goes low will clock in the
MSB of the input word.
When each serial word is complete, the value is stored
in the SRAM at the address indicated and the control
bits are saved. Note that data may be corrupted if
CS
is
not held low for an integer multiple of 24 bits.
All of the digital inputs include Schmitt-trigger buffers to
accept slow-transition interfaces. Their switching
threshold is compatible with TTL and most CMOS logic
levels.
Serial Input Data Format and
Control Codes
The 24-bit serial input format, shown in Figure 4, compris-
es of 16 data bits (D15
–
D0), five address bits (A4
–
A0),
two control bits (C1, C0), and a fill zero. The address
code selects the output channel as shown in Table 2. The
control code configures the device as follows:
1) If C1 = 1, Immediate Update Mode is selected.
If C1 = 0, Burst Mode is selected.
2) If C0 = 0, the internal sequencer clock is selected. If
C0 = 1, the external sequencer clock is selected.
This must be repeated with each data word to main-
tain external input.
