• Manufacturer: Maxim

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.
