10.11.2 Master Receiver mode
In the master receiver mode, a number of data bytes are received from a slave transmitter
(see
START condition has been transmitted, the interrupt service routine must load I2DAT with
the 7-bit slave address and the data direction bit (SLA+R). The SI bit in I2CON must then
be cleared before the serial transfer can continue.
When the slave address and the data direction bit have been transmitted and an
acknowledgment bit has been received, the serial interrupt flag (SI) is set again, and a
number of status codes in I2STAT are possible. These are 0x40, 0x48, or 0x38 for the
master mode and also 0x68, 0x78, or 0xB0 if the slave mode was enabled (AA = 1). The
appropriate action to be taken for each of these status codes is detailed in
a Repeated START condition (state 0x10), the I
transmitter mode by loading I2DAT with SLA+W.
