O
Request to Send or general purpose output (active low). If
this pin is not needed for modem communication, then it can
be used as a general I/O. If it is not used, leave it uncon-
nected.

Clear to Send or general purpose input (active low). If this
pin is not needed for modem communication, then it can be
used as a general I/O. If it is not used, connect it to VCC.

then it can be used as a general I/O. If it is not used, leave it
unconnected.

ANCILLARY SIGNALS
CLK
-
12
-
12
-
I
External Clock Input. This function is associated with 28 pin
PDIP and 28 pin PLCC ST16C1451 packages only. An
external clock must be connected to this pin to clock the
baud rate generator and internal circuitry.
XTAL1

-
12
-
15
I
Crystal or external clock input. See
Figure 4
for typical
oscillator connections.
XTAL2

16
O
Crystal or buffered clock output. See
Figure 4
for typical
oscillator connections.
RESET

I
Reset Input (active high). When it is asserted, the UART
configuration registers are reset to default values, see
Table 6
.
RST
-
17
-
17
22
O
Reset Output (active high). This output is only available on
the ST16C1451. When IER bit-5 is a logic 0, RST will follow
the logical state of the RESET pin. When IER bit-5 is a logic
1, the user may send software (soft) resets via MCR bit-2.
Soft resets from MCR bit-2 are “ORed” with the state of the
RESET pin.
VCC
