MICRONAS INTERMETALL

Name

Default

Function

FP Sub

address

FP Display Control Register, BCL

h’d4

BCL threshold current, 0..2047 (max ADC output ~1152)

1000

BCLTHR

h’d2

BCL time constant. 0..15 ––> 0.5 .. 100msec

BCLTM

h’d3

BCL loop gain. 0..1023. Bit 11 must be always set to 1.

BCLG

h’d5

BCL minimum contrast. 0..1023

307

BCLMIN

h’75

Test register for BCL/EHT comp. function, register value:

stop ADC offset compensation

x>1

use x in place of input from Measurement ADC

BCLTST

FP Display Control Register, Deflection

h’73

interlace offset, –2048..2047

this value is added to the SAWTOOTH output during one field

INTLC

h’72

discharge sample count for deflection retrace,

SAWTOOTH DAC output impedance is reduced for DSCC lines after

vertical retrace.

DSCC

h’8f

vertical discharge value,

SAWTOOTH output value during discharge operation, typically same as

A0 init value for sawtooth

–1365

DSCV

h’7b

EHT (electronic high tension) compensation coefficient. 0..1023

EHT

h’7a

EHT time constant. 0..15 ––> 0.5 .. 100msec

EHTTM

FP Display Control Register, Vertical Sawtooth

h’80

DC offset of SAWTOOTH output,

this offset is independent of EHT compensation.

OFS

h’8b

accu0 init value

–1365

h’8c

accu1 init value

900

h’8d

accu2 init value

h’8e

accu3 init value

FP Display Control Register, East–West Parabola

h’9b

accu0 init value

–1121

h’9c

accu1 init value

219

h’9d

accu2 init value

479

h’9e

accu3 init value

–1416

h’9f

accu4 init value

1052

1) The white drive values will become active only after writing the blue value WDB, latching of new values is indicated

by setting the MSB of WDB.
