FAQs: 

Q1: OK, I've got the documentation, but still have trouble mapping segments to code. Help?
A1: No problem, this can get a bit fuzzy.

Imagine you want to make a '3' appear in the right-most digit (digit 7, see page 4). This would require the illumination of segments A, B, C, D, G, and M (see page 4). This means that 7A, 7B, 7C, 7D, 7G, and 7M must have 1s in the segment registers, and all other 7x segments must be a zero.

On the ES449, these segments are provided at pins 23 through 26 (page 5). Per page 6, and the ES449 schematic, pins 23 through 26 are connected to segment lines S12 through S15, in reverse order.

Now, flip your brain inside out once more. The following means that S12 through S15 have to get the following bit pattern:

S12: 0x02 (segs N:M:K:J)
S13: 0x0F (segs D:C:B:A)
S14: 0x04 (segs P:Q:G:H)
S15: 0x00 (segs x:E:F:x)

This means that the LCD registers must be set as follows:

LCDM7 = 0xF2; // S21:S20
LCDM8 = 0x04; // S23:S22

Q2: What frame rate should be used with this LCD?
A2: The LCD frame rate isn't tightly specified, it is more a function of the driver IC and a subjective evaluation.

Q3: What is the mounted height of this display?
A3: The flush-mounted height from the top of the PCB to the top of the glass is 0.200".

Q4: What is the overall height of the display?
A4: The original overall height of early units was 6.5mm, as indicated in the specification. That height has now changed to 8.9mm to accomodate thicker backlights for the SBLCDA2T transflective version.
