12.8.10 I
12.9.1 Master Transmitter mode
Although the DATA_BUFFER register is primarily intended for use in monitor mode with
the ENA_SCL bit = ‘0’, it will be available for reading at any time under any mode of
operation.
Table 220. I
The four mask registers each contain seven active bits (7:1). Any bit in these registers
which is set to ‘1’ will cause an automatic compare on the corresponding bit of the
received address when it is compared to the I2ADDRn register associated with that mask
register. In other words, bits in an I2ADDRn register which are masked are not taken into
account in determining an address match.
On reset, all mask register bits are cleared to ‘0’.
The mask register has no effect on comparison to the General Call address (“0000000”).
Bits(31:8) and bit(0) of the mask registers are unused and should not be written to. These
bits will always read back as zeros.
When an address-match interrupt occurs, the processor will have to read the data register
(I2DAT) to determine what the received address was that actually caused the match.
Table 221. I
In a given application, the I
mode, the I
address. If one of these addresses is detected, an interrupt is requested. If the processor
wishes to become the bus master, the hardware waits until the bus is free before the
master mode is entered so that a possible slave operation is not interrupted. If bus
arbitration is lost in the master mode, the I
immediately and can detect its own slave address in the same serial transfer.
In this mode data is transmitted from master to slave. Before the master transmitter mode
can be entered, the I2CONSET register must be initialized as shown in
must be set to 1 to enable the I
acknowledge any address when another device is master of the bus, so it can not enter
