The TMP86FS49AFG has a serial bus interface which employs an I
The serial interface is connected to an external devices through SDA and SCL.
The serial bus interface pins are also used as the port. When used as serial bus interface pins, set the output latches
Note 1: The serial bus interface can be used only in NORMAL1/2 and IDLE1/2 mode. It can not be used in IDLE0,
Note 2: The serial bus interface can be used only in the Standard mode of I
Note 3: Please refer to the I/O port section about the detail of setting port.
The following registers are used for control the serial bus interface and monitor the operation status.
A serial bus interface circuit has a software reset function, when a serial bus interface circuit is locked by an exter-
To reset the serial bus interface circuit, write “10”, “01” into the SWRST (Bit1, 0 in SBICRB).
And a status of software reset canbe read from SWRMON (Bit0 in SBISRA).
