SMB0 (system management bus)
(1) SMB0 functions
SMB0 has the following two types of modes.
Operation stopped mode
SMB mode (supporting multiple masters)
(a) Operation stopped mode
This mode is used when serial transfer is not performed. Power consumption is minimized in this mode.
(b) SMB mode (supporting multiple masters)
This mode is used for performing 8-bit data transmission to several devices, using a serial clock (SCL0)
line and a serial data bus (SDA0) line.
In this mode, which conforms to the SMB format, start conditions, data, stop conditions can be output on
the serial data bus during transmission. Moreover, these data can be automatically detected by hardware
during reception.
In SMB0, SCL0 and SDA0 are open-drain outputs, and therefore a pull-up resistor is required for the
serial clock line and serial data bus line.

C (Inter IC) bus standard mode or high-speed mode can be specified by software in SMB mode.
Figure 7-37 shows the block diagram of SMB0.
