TMAG5111 Side

U13, C13, U12, C12, and R32 perform the same functions as the respective components from the TMAG5110 side but for the TMAG5111 signal path.

R31 and C10 create an RC filter which are combined with a dual Schmitt-Trigger buffer (U9, SN74LVC2G14) and a single 2-input Exclusive-OR gate (U10, SN74LVC1G86) to create an edge detection circuit. The edge detection circuit is used to convert the rising edge up/down counter (U13) to a dual edge up down counter to count every clock transition from the TMAG5111 (U11).
