† _{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 for the
TMS320LC546PZ (100-pin TQFP package).
For the ’LC546 (100-pin TQFP package), the letter B in front of CLKR, FSR, DR, FSX, and DX denotes buffered
serial port (BSP). No letter in front of CLKR, FSR, DR, FSX, and DX denotes standard serial port.
