Description
Data bus (bi-directional). These pins are the 8-bit, 3-State data bus
for transferring information to or from the controlling CPU. D0 is the
least significant bit and the first data bit in a transmit or receive serial
data stream.
Data Set Ready (Active-LOW). These inputs are associated with
individual UART channels, A through D. A logic 0 on this pin indicates
the modem or data set is powered-on and is ready for data exchange
with the UART. This pin has no effect on the UART’s transmit or
receive operation.
Data Terminal Ready (Active-LOW). These outputs are associated
with individual UART channels, A through D. A logic 0 on this pin
indicates that the SC16C554/554D is powered-on and ready. This pin
can be controlled via the modem control register. Writing a logic 1 to
MCR[0] will set the DTR output to logic 0, enabling the modem. This
pin will be a logic 1 after writing a logic 0 to MCR[0], or after a reset.
This pin has no effect on the UART’s transmit or receive operation.
Signal and power ground.
Interrupt A, B, C, D (Active-HIGH). This function is associated with
the 16 mode only. These pins provide individual channel interrupts
INTA-INTD. INTA-INTD are enabled when MCR[3] is set to a logic 1,
interrupts are enabled in the interrupt enable register (IER), and
when an interrupt condition exists. Interrupt conditions include:
receiver errors, available receiver buffer data, transmit buffer empty,
or when a modem status flag is detected. When the 68 mode is
selected, the functions of these pins are re-assigned. 68 mode
functions are described under their respective name/pin headings.
Interrupt Select (Active-HIGH, with internal pull-down). This
function is associated with the 16 mode only. When the 16 mode is
selected, this pin can be used in conjunction with MCR[3] to enable
or disable the 3-State interrupts, INTA-INTD, or override MCR[3] and
force continuous interrupts. Interrupt outputs are enabled
continuously by making this pin a logic 1. Making this pin a logic 0
allows MCR[3] to control the 3-State interrupt output. In this mode,
MCR[3] is set to a logic 1 to enable the 3-State outputs. This pin is
disabled in the 68 mode. Due to pin limitations on the 64-pin
packages, this pin is not available. To cover this limitation, the
SC16C654DIB64 version operates in the continuous interrupt enable
mode by bonding this pin to V
operates with MCR[3] control by bonding this pin to GND.
Input/Output Read strobe (Active-LOW). This function is
associated with the 16 mode only. A logic 0 transition on this pin will
load the contents of an internal register defined by address bits
A0-A2 onto the SC16C554/554D data bus (D0-D7) for access by
external CPU. This pin is disabled in the 68 mode.
