Acknowledge Registers

The acknowledge registers are used to acknowledge the interruption source. When ACK = 1, the

I²C master acknowledges the corresponding interrupt.

Warning : These 2 registers can be written by the I2C but can't be read. Each bit is reset by the I2C

slave (stv2310) one clock period after an high level has been detected.

Bit Name

Function

VBI_EQUALCOE

FF[2:0]

These bits select precomputed coefficients for the equaliser or let the equaliser select automatically the

best set of coefficients or impose to the equaliser the sets of coefficients programmed

000: use set 1 of coefficients

001: use set 2 of coefficients

010: use set 3 of coefficients (central or no equaliser)

011: use set 4 of coefficients

100: equaliser in automatic mode

101: use set 5 of ceofficients

110: use programmed registers (see registers VBICONT0D and VBICONT0E) for the equaliser coefficients.
