TL16C550B Overview
The TL16C550B and the TL16C550BI are functional upgrades of the TL16C450 asynchronous munications element (ACE). Functionally identical to the TL16C450 on power up (character mode†), the TL16C550B and TL16C550BI can be placed in an alternate mode (FIFO) to relieve the CPU of excessive software overhead. In this alternate FIFO mode, internal FIFOs are activated allowing 16 bytes (plus 3 bits of error data per byte in...
