External Crystal Input:
XIN input is used in conjunction with XOUT to form a feedback circuit for the baud
rate generator's oscillator. If a clock signal is generated off-chip, then it should drive
the baud rate generator through this pin. Refer to Section 7.1 CLOCK INPUT.
External Crystal Output:
XOUT output is used in conjunction with XIN to form a feedback circuit for the baud
rate generator's oscillator. If the clock signal is generated off-chip, then this pin is
unused. Refer to Section 7.1 CLOCK INPUT.
Master Reset:
When MR input is high, it clears all the registers including Tx and Rx serial shift
registers (except the Receiver Buffer, Transmitter Holding, and Divisor Latches).
The output signals, such as OUT2, RTS, DTR, INTR, and SOUT are also affected
by an active MR input. (Refer to Table 26 and Section 7.2 RESET).
