• Manufacturer Part Number: SC28C198A1A
• Description: Octal UART for 3.3V and 5V supply voltage
• Manufacturer: PHILIPS [NXP Semiconductors]

Philips Semiconductors
The registers of the SC28L198 are partitioned into two groups: those
used in controlling data channels and those used in handling the
actual data flow and status. Below is shown the general
configuration of all the register addressed. The ”Register Map
Summary” shows the configuration of the lower four bits of the
address that is the same for the individual UARTs. It also shows the
addresses for the several in the address space of UART A and
