† NC = No connection

‡ DVDD is the power supply for the I/O pins while CVDD is the power supply for the core CPU, and VSS is the ground for both the I/O pins and the

core CPU.

For the 144-pin TQFP, the letter B in front of CLKRn, FSRn, DRn, CLKXn, FSXn, and DXn pin names denotes

buffered serial port (BSP), where n = 0 or 1 port. The letter T in front of CLKR, FSR, DR, CLKX, FSX, and DX

pin names denotes time-division multiplexed (TDM) serial port.
