† _{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.
The ’54x signal descriptions table lists each terminal name, function, and operating mode(s) for the
TMS320C542PGE/’LC542PGE (144-pin TQFP packages).
For the ’C542/’LC542 (144-pin TQFP packages), the letter B in front of CLKR, FSR, DR, CLKX, FSX, and DX
pin names denotes buffered serial port (BSP). The letter T in front of CLKR, FSR, DR, CLKX, FSX, and DX pin
names denotes time-division multiplexed (TDM) serial port.
