I
16/68 Interface type select (input with internal  
pull-up). This input provides the 16 (Intel) or 68  
(Motorola) bus interface type select. The functions of  
IOR, IOW, INTA to INTD, and CSA to CSD are  
re-assigned with the logical state of this pin. When this  
pin is a logic 1, the 16 mode interface (16C554) is  
selected. When this pin is a logic 0, the 68 mode  
interface (68C554) is selected. When this pin is a logic  
0, IOW is re-assigned to R/W, RESET is re-assigned to  
RESET, IOR is not used, and INTA to INTD are  
connected in a wire-OR configuration. The wire-OR  
outputs are connected internally to the open drain IRQ  
signal output. This pin is not available on 64-pin  
packages which operate in the 16 mode only.

Address 3 to Address 4 select bits. When the 68  
mode is selected, these pins are used to address or  
select individual UARTs (providing CS is a logic 0). In  
the 16 mode, these pins are re-assigned as chip  
selects, see CSB and CSC.

Carrier Detect (active LOW). These inputs are  
associated with individual UART channels A through D.  
A logic 0 on this pin indicates that a carrier has been  
detected by the modem for that channel.

Chip Select (active LOW). In the 68 mode, this pin  
functions as a multiple channel chip enable. In this  
case, all four UARTs (A to D) are enabled when the CS  
pin is a logic 0. An individual UART channel is selected  
by the data contents of address bits A3 to A4. when the  
16 mode is selected (68-pin devices), this pin functions  
as CSA (see definition under CSA, CSB).

Chip Select A, B, C, D (active LOW). This function is  
associated with the 16 mode only, and for individual  
channels ‘A’ through ‘D’. When in 16 mode, these pins  
enable data transfers between the user CPU and the  
SC16C554B/554DB for the channel(s) addressed.  
Individual UART sections (A, B, C, D) are addressed by  
providing a logic 0 on the respective CSA to CSD pin.  
When the 68 mode is selected, the functions of these  
pins are re-assigned. 68 mode functions are described  
under their respective name/pin headings.
