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.

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

12

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

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 8
.
RST
-
17
-
17
22
O
Reset Output (active high). This output is only available on
the ST16C1551. 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.
