† _{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.
