Figure 7. 16-Bit Write Transmission to the MAX6852
If fewer or greater than 16 bits are clocked into the
MAX6852 between taking CS low and taking CS high
again, the MAX6852 stores the last 16 bits received,
including the previous transmission(s). The general
case is when n bits (where n > 16) are transmitted to
the MAX6852. The last bits comprising bits {n-15} to {n}
are retained and are parallel loaded into the 16-bit latch
as bits D15 to D0, respectively (Figure 8).
Reading Device Registers
Any register data within the MAX6852 may be read by
sending a logic high to bit D15. The sequence is:
1) Take SCLK low.
2) Take CS low. This enables the internal 16-bit shift
register.
3) Clock 16 bits of data into DIN, D15 first to D0 last,
observing the setup and hold times. Bit D15 is high,
indicating a read command, and bits D14 through
D15 = 0
D8 contain the address of the register to read. Bits
D7 to D0 contain dummy data, which is discarded.
4) Take CS high. Positions D7 through D0 in the shift
register are now loaded with the data in the register
addressed by bits D15 through D8.
5) Take SCLK low.
6) Issue another read or write command (which can be
no-op), and examine the bit stream at DOUT; the
first 8 bits contain the address of the register that
was read ( Note: The MSB, which was transmitted as
a 1 for a read command, may read back either as a
1 or a zero). The second 8 bits are the contents of
the register addressed by bits D14 through D8 in
Step 3.
VFD Driver Serial Interface
The VFD driver interface on the MAX6852 is a serial
interface using three output pins, VFLOAD, VFCLK, and
VFDOUT (Figure 9) to drive industry-standard, shift-reg-
