# common make targets for compiling fx2 firmware
#
# In your Makefile, define:
# SOURCES: list of c files to compile
# A51_SOURCES: list of any a51 files.
# DEPS: list of any depedancies (like auto-generated header files) that need
# generated prior to compiling. You must provide the target definition
# for any DEPS you define.
# BASENAME: name of your firmware file, i.e., myfirmware, but not myfirmware.c
#
# Leave these alone or redefine as necessary to customize firmware.
# (Redefine after including this makefile)
# VID vendor id
# PID product id
# LIBS optional additional libraries to link with the firmware.

# CODE_SIZE: Default --code-size 0x3c00
# XRAM_SIZE: Default --xram-size 0x0200
# XRAM_LOC: Default --xram-loc 0x3c00

Discard the value that was read from I2DAT.
6. Wait for DONE=1. If BERR=1, go to step 1.
7. Read the just-received byte of data from I2DAT. This read also initiates the next read transfer.
8. Repeat steps 6 and 7 for each byte until ready to read the second-to-last byte.
9. Wait for DONE=1. If BERR=1, go to step 1.
10. Before reading the second-to-last I2DAT byte, set LASTRD=1.
11. Read the second-to-last byte from I2DAT. With LASTRD=1, this initiates the final byte read on
the bus.
12. Wait for DONE=1. If BERR=1, go to step 1.
13. Set STOP=1.
14. Read the final byte from I2DAT immediately (the next instruction) after setting the STOP bit. By
reading I2DAT while the "stop" condition is being generated, the just-received data byte will be
retrieved without initiating an extra read transaction (nine more SCL pulses) on the I²Cbus.
