3.18.2 I
2
C Interface Boot Load Access
At power on reset the I
2
C interface boot loader loads the
VID/PID/DID and configuration bytes and up to 16 kBytes of
program/data. The available RAM spaces are 16 kBytes from
0x0000–0x3FFF and 512 bytes from 0xE000–0xE1FF. The 8051
is reset. I
2
C interface boot loads only occur after power on reset.
3.18.3 I
2
C Interface General Purpose Access
The 8051 can control peripherals connected to the I
2
C bus using
the I2CTL and I2DAT registers. FX2LP18 provides I
2
C master
control only, it is never an I
2
C slave.
4. Pin Assignments
Figure 6
identifies all signals for the package. It is followed by the
pin diagram.Three modes are available: Port, GPIF master, and
Slave FIFO. These modes define the signals on the right edge
of the diagram. The 8051 selects the interface mode using the
IFCONFIG[1:0] register bits. Port mode is the power on default
configuration.
