Octal UART with TTL compatibility at 3.3V
and 5V supply voltages
1995 May 1

Limitations:
Minimum RESETN pin pulse width is 10 SClk cycles
after Vcc
reaches operational range
The user must allow a minimum of 6 SClk cycles to elapse after
a reset (RESETN pin or CRa initiated) of the device terminates
before initiating a new bus cycle.
