ST16C552/552A
Rev. 3.40
The rich feature set of the 552/552A is available
through internal registers. Selectable receive FIFO
trigger levels, selectable TX and RX baud rates,
modem interface controls, and a power-down mode
are all standard features. Following a power on reset
or an external reset, the 552/552A is software compat-
ible with the previous generation, 16C452.
FUNCTIONAL DESCRIPTIONS
Functional Modes
Two functional user modes are selectable for the 552/
552A package. The first of these provides the dual
UART functions, while the other provides the func-
tions of a parallel printer interface. These features are
available through selection at the package interface
select pins.
UART A-B Functions
The UART mode provides the user with the capability
to transfer information between an external CPU and
the 552/552A package. A logic 0 on chip select pins -
CSA or -CSB allows the user to configure, send data,
and/or receive data via the UART channels A-B.
Printer Port Functions
The Printer mode provides the user with the capability
to transfer information between an external CPU and the
552/552A parallel printer port. A logic 0 on chip select
pin -CSP allows the user to configure, send data, and/
or receive data via the bi-directional parallel 8-bit data
bus, PD0-PD7.
Internal Registers
The 552/552A provides 12 internal registers for monitor-
ing and control of the UART functions and another 6
registers for monitoring and controlling the printer port.
These resisters are shown in Table 4 below. The UART
registers function as data holding registers (THR/RHR),
interrupt status and control registers (IER/ISR), a FIFO
control register (FCR), line status and control registers
(LCR/LSR), modem status and control registers (MCR/
MSR), programmable data rate (clock) control registers
(DLL/DLM), and a user assessable scratchpad register
(SPR). The printer port registers functions data holding
registers (PR), I/O status register (SR), I/O select
register (IOSEL), and a command and control register
(COM/CON). Register functions are more fully de-
scribed in the following paragraphs.
