ST92141 - ANALOG TO DIGITAL CONVERTER (ADC)

LOWER THRESHOLD REGISTERS (LTiR)

The two Lower Threshold registers are used to

store the user programmable lower threshold 8-bit

values, to be compared with the current conver-

sion results, thus setting the lower window limit.

CHANNEL 6 LOWER THRESHOLD REGISTER

(LT6R)

R248 - Read/Write

Reset Value: undefined

Bit 7:0 = LT6.[7:0]: Channel 6 Lower Threshold

CHANNEL 7 LOWER THRESHOLD REGISTER

(LT7R)

R249 - Read/Write

Reset Value: undefined

Bit 7:0 = LT7.[7:0]:

Channel 7 Lower Threshold

UPPER THRESHOLD REGISTERS (UTIR)

The two Upper Threshold registers are used to

store the user programmable upper threshold 8-bit

values, to be compared with the current conver-

sion results, thus setting the upper window limit.

CHANNEL 6 UPPER THRESHOLD REGISTER

(UT6R)

R250 - Read/Write

Reset Value: undefined

Bit 7:0 = UT6.[7:0]:

Channel 6 Upper Threshold
