Pin
Signal Type
Pin Description
SYMBOL DESCRIPTION
INT A/B
34,17
O
Interrupt output A/B. (active high) This pin goes high (when
enabled by the interrupt enable register) whenever a re-
ceiver error, receiver data available, transmitter empty, or
modem status condition flag is detected.
MF* A/B
35,19
O
OP2* (interrupt enable), BAUDOUT* and RXRDY* outputs.
These outputs are multiplexed via Alternate Function Reg-
ister. When output enable function is selected the MF* pin
stays high when INT out pin is set to three state mode and
goes low when INT pin is enabled. See bit-3 modem control
register (MCR bit-3). When BAUDOUT function is selected,
the 16 X TX/RX Baud rate clock output is generated.
RXRDY function can be selected to use to request a DMA
transfer of data from the Receive data FIFO. OP2* is the
default signal and it is selected immediately after master
reset or power-up.
TXRDY* A/B
1,32
O
Transmit ready. (active low) This pin goes high when the
transmit FIFO of the ST16C2552 is full. It can be used as a
single or multi-transfer.
RTS* A/B
36,23
O
Request to send A/B (active low). To indicate that the
transmitter has data ready to send. Writing a “1” in the
modem control register (MCR bit-1 ) will set this pin to a low
state. After the reset this pin will be set to high. Note that
this pin does not have any effect on the transmit or receive
operation.
DTR* A/B
37,27
O
Data terminal ready A/B (active low). To indicate that
ST16C2552 is ready to receive data. This pin can be
controlled via the modem control register (MCR bit-0).
Writing a “1” at the MCR bit-0 will set the DTR* output to low.
This pin will be set to high state after writing a “0” to that
register or after the reset . Note that this pin does not have
any effect on the transmit or receive operation.
RESET
21
I
Master reset. (active high) A high on this pin will reset all the
outputs and internal registers. The transmitter output and
the receiver input will be disabled during reset time.
