3.15 Serial Bus Interface (SBI)
The TMP92CZ26A has a 1-channel serial bus interface which an I
2
C bus mode. This circuit
supports only I
2
C bus mode (Multi master).
The serial bus interface is connected to an external device through PV6 (SDA) and PV7 (SCL)
in the I
2
C bus mode.
Each pin is specified as follows.
PVFC2<PV7F2, PV6F2> PVCR<PV7C, PV6C> PVFC<PV7F, PV6F>
