80C51 with 512 B/1 kB/2 kB RAM, dual I2C-bus, SPI
6.4.4 I2C-bus status register
This is a read-only register. It contains the status code of the I2C-bus interface. The least
three bits are always 0. There are 26 possible status codes. When the code is F8H, there
is no relevant information available and SI bit is not set. All other 25 status codes
correspond to defined I2C-bus states. When any of these states entered, the SI bit will be
set. Refer to Table 22 to Table 25 for details.
6.4.5 I2C-bus operation modes
6.4.5.1
Master transmitter mode
In this mode data is transmitted from master to slave. Before the Master Transmitter mode
can be entered, S1CON must be initialized as follows:
CR2:0 define the bit rate (See Table 17). ENS1 must be set to 1 to enable the I2C-bus
function. If the AA bit is 0, it will not acknowledge its own slave address or the general call
address in the event of another device becoming master of the bus and it can not enter
slave mode. STA, STO, and SI bits must be cleared to 0.
The first byte transmitted contains the slave address of the receiving device (7 bits) and
the data direction bit. In this case, the data direction bit (R/W) will be logic 0 indicating a
write. Data is transmitted 8 bits at a time. After each byte is transmitted, an acknowledge
bit is received. START and STOP conditions are output to indicate the beginning and the
end of a serial transfer.
