8.2 MIS23x Registers
8.2.42 Encoder_Typ
8.2.43 Afzup_WriteBits
Description: When changing values for the analogue input filter parameters, this register is used in
combination with registers 102-106. First, all of the registers 102-106 must be loaded
with the values to be used for one or more analogue input filters.
Then the lower eight bits in this register are set to select which inputs the parameters in
registers 102-106 should control. The firmware will detect this and copy the parameter
values from registers 102-106 to internal storage. Once this has been completed, the
firmware sets bit 15 in this register to show that registers 102-106 are free to receive
new values for programming the remaining inputs with other filter parameters. To use
the same filtering for all analogue inputs, this register can be loaded with 255 (hex FF).
8.2.44 Afzup_ReadIndex
Description: This register makes it possible to read back the analogue input filter parameters for one
analogue input at a time. To select a new input, write a value of 1 to 8 to this register and
wait for bit 15 to be set high.
When bit 15 has been set by the firmware, the registers 102-106 have been loaded with
the filter parameters currently used by that analogue input.
8.2.45 Afzup_ConfMin
Description: The minimum confidence limits for analogue inputs are set and read back using this reg-
ister in combination with the read and write ‘command’ registers 100 and 101.
If a new raw sample value is less than the value in this register, it is simply discarded and
the filtered input value in registers 81-88 will not change. A value of zero in this register
will effectively disable the minimum confidence check.
