NC – No internal connection
† _{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 549 signal descriptions table lists each terminal name, function, and operating mode(s) for the 164-pin
ceramic quad flatpack (CQFP).
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.
