Before a register access, PHY devices generally require a preamble of 32 ones to be sent by the MAC on the MDIO line. The access consists of 16 control bits, followed by 16 data bits. The control bits consist of 2 start bits, 2 access type bits (read or write), the PHY address (5 bits), the register address (5 bits), and 2 "turnaround" bits.
ULN2003A pinout Simplified ULN2003A logical pinout diagram. The ULN2003A is an integrated circuit produced by Texas Instruments. It consists of an array of seven NPN Darlington transistors capable of 500 mA, 50 V output. It features common-cathode flyback diodes for switching inductive loads (such as servomotors).
Society of Automotive Engineers standard SAE J1587 is an automotive diagnostic protocol standard developed by the Society of Automotive Engineers (SAE) for heavy-duty and most medium-duty vehicles built after 1985.
JTAG (named after the Joint Test Action Group which codified it) is an industry standard for verifying designs of and testing printed circuit boards after manufacture.. JTAG implements standards for on-chip instrumentation in electronic design automation (EDA) as a complementary tool to digital simulation. [1]
Ebot IDE was developed by CreativeBits Co., and was designed to teach programming in a simple way. The software allows users to program using a command-line interface or a graphical interface, with a Data Lab to analyze the records, a serial Monitor to view current readings, and an PC control Interface to add more advanced options.

ICSPCLK - Clock line of the serial data interface. This line swings from GND to V dd and is always driven by the programmer. Data is transferred on the falling edge. ICSPDAT - Serial data line. The serial interface is bi-directional, so this line can be driven by either the programmer or the PIC depending on the current operation.
