Dual UART with 16 bytes of transmit and receive FIFOs and IrDA
Address 0 select bit. Internal register address selection.
Address 1 select bit. Internal register address selection.
Address 2 select bit. Internal register address selection.
Chip Select A, B (Active-LOW). This function is associated with individual
channels, A through B. These pins enable data transfers between the user
CPU and the SC16C2550 for the channel(s) addressed. Individual UART
sections (A, B) are addressed by providing a logic 0 on the respective CSA,
CSB pin.
Data bus (bi-directional). These pins are the 8-bit, 3-State data bus for
transferring information to or from the controlling CPU. D0 is the least
significant bit and the first data bit in a transmit or receive serial data
stream.
Signal and power ground.
