between grids. Thus, image ghosting is avoided. If a
display has very slow phosphor, then the allowed decay
time can be doubled by not using a 15/16 duty cycle.
VFBLANK Polarity Register
The VFBLANK polarity register sets the active level of
the VFBLANK output pin (Table 26).
No-Op Register
A write to the no-op register is ignored.
Display-Test and Device ID Register
Writing the display-test and device ID register switches
the drivers between one of two modes: normal and dis-
play test. Display-test mode turns all segments and
annunciators on and sets the duty cycle to 7/16 (half-
power) (Table 27).
Reading the display-test and device ID register returns
the MAX6852 device ID 0b0000 011 that identifies the
driver type, plus the display-test status in the LSB.
Output Shift-Limit Register
The output serial interface is used to transfer display
data from the MAX6852 to the display driver. The serial
interface bit-stream output length is programmable up
to 122 bits, which are labeled DD0 – DD121. Set the
number of bits with the shift-limit register, address
0x0E. If the shift-limit register is written with an out-of-
range value 0x7A to 0xFF, then the value 0x79 is stored
instead. Table 28 shows the shift-limit register.
Output Map
The output map comprises 122 words of 7-bit RAM.
The output map data should be written when the
MAX6852 is configured after power-up. Table 29 shows
the output map RAM codes.
