I’m the owner of the kyt cy3271 and I’m working about psoc CY8C27443-24PVXI of the RF Expansion card.
I’ve the example of a filter notch made on cy8c29466-24 PXI, it has been used a LPF2 duly assessed with an excel working paper ( sent as enclosure). I would like to know what is the capacity Cpp, because in the datasheet of the LPF2 it is not present. Moreover in the file main.asm the following code is present, and I don’t know what it is for, ‘cause I don’t know the assembler very well:

; Assembly main line

include "" ; part specific constants and macros
include "" ; Constants & macros for SMM/LMM and Compiler
include "" ; PSoC API definitions for all User Modules

export _main

mov A, reg[ASD11CR3]
and A, ~0x04
mov reg[ASD11CR3],A
mov A, 0x03
call PGA_1_Start
mov A, 0x03
call LPF2_1_Start
call Counter24_1_Start
mov a, reg[ASD11CR1]
or a, 0x1f
mov reg[ASD11CR1], a

jmp .terminate
