C-BUS REGISTERS
The TZA3015HW can be programmed via the I
2
C-bus if pin UI = HIGH or leaving the pin open-circuit. The I
2
C-bus
registers can be accessed via the 2-wire I
2
C-bus interface using pins SCL and SDA if pin CS = HIGH during read or write
actions. The I
2
C-bus address of the TZA3015HW can be found in Table 2.
