Table 12 shows the six sequential write commands
required to set a MAX6852 ’ s font character RAM02 with
the data to display character 2 given in Table 7.
Cursor Register
The cursor register controls the behavior of the cursor
segments (Table 13). The MAX6852 controls 48 cursors
in 48/1 mode, and 96 cursors in 96/2 mode. The cursor
register selects one digit ’ s cursor to be lit either contin-
uously or blinking. All the other digits ’ cursors are off.
The 7 least significant bits (LSBs) of the cursor register
identify the cursor position. The MSB is clear for the
cursor to be on continuously, and set for the cursor to
be lit only during the first half of each blink period.
The valid cursor position address range is contiguous:
0 to 47 (0x00 to 0x2F) for the 1st digit row, and 48 to 95
(0x30 to 0x5F) for the 2nd digit row. If the cursor regis-
ter is programmed with an out-of-range value of 95 to
127 (0x60 to 0x7F), then all cursors are off.
Annunciator Registers
The annunciator registers are organized in bytes, with
each segment of each grid being represented by 2
bits. Thus, the four annunciators segments allowed for
each grid are represented by exactly 1 byte (Table 14).
Annunciators are only available in 48/1 mode. The
annunciator address map is shown in Table 4.
Configuration Register
The configuration register is used to enter and exit shut-
down, lock the key VFD configuration settings, select
the blink rate, globally clear the digit and annunciator
data, reset the blink timing, and select between 48/1
and 96/2 display modes (Table 15).
