Default values: 0000h
LED segment-display register 2 is a 16-bit read/write
register. When the SEG_SEL bit (in the control register)
is set to 1, the MAX1497/MAX1499 provide direct
access to individual LED segments. The bits in the LED
segment-display register determine if a segment is on
or off. Write a zero to turn on a segment and a 1 to turn
off a segment.
C1: Segment C driver bit of digit 1. The default value
turns on the LED segment.
B1: Segment B driver bit of digit 1. The default value
turns on the LED segment.
MINUS: Segment minus driver bit. The default value
turns on the LED minus segment. Setting this bit to 1
enables the plus sign on the LED display.
DP3: Segment DP driver bit of digit 3. The default value
turns on the LED segment.
E2: Segment E driver bit of digit 2. The default value
turns on the LED segment.
F2: Segment F driver bit of digit 2. The default value
turns on the LED segment.
D2: Segment D driver bit of digit 2. The default value
turns on the LED segment.
G2: Segment G driver bit of digit 2. The default value
turns on the LED segment.
A2: Segment A driver bit of digit 2. The default value
turns on the LED segment.
C2: Segment C driver bit of digit 2. The default value
turns on the LED segment.
B2: Segment B driver bit of digit 2. The default value
turns on the LED segment.
DP4: Segment DP driver bit of digit 4. The default value
turns on the LED segment (MAX1499 only).
E3: Segment E driver bit of digit 3. The default value
turns on the LED segment (MAX1499 only).
F3: Segment F driver bit of digit 3. The default value
turns on the LED segment (MAX1499 only).

C3: Segment C driver bit of digit 3. The default value
turns on the LED segment (MAX1499 only).
B3: Segment B driver bit of digit 3. The default value
turns on the LED segment (MAX1499 only).
BC_: Segment B and C driver bit of digit 3 (3.5 digits)
or Digit 4 (4.5 digits). The default value turns on the
LED segment.
X: Don’t care.
