Signal
Description
Pin No.
Name
Type
1
XTALN
O/P
The inverted output of the on-chip oscillator.
2
XTAL/CLOCK
I/P
The input to the on-chip oscillator, for external
Xtal circuit or clock.
3
SERIAL CLOCK
I/P
The "C-BUS" serial clock input. This clock,
produced by the μController, is used for transfer
timing of commands and data to and from the
device. See "C-BUS" Timing Diagram (Figure
4).
4
COMMAND DATA
I/P
The "C-BUS" serial data input from the
μController. Data is loaded into this device in
8-bit bytes, MSB (B7) first, and LSB (B0) last,
synchronised to the SERIAL CLOCK. See
"C-BUS" Timing Diagram (Figure 4).
5
REPLY DATA
O/P
The "C-BUS" serial data output to the
μController. The transmission of REPLY DATA
bytes is synchronised to the SERIAL CLOCK
under the control of the CSN input. This 3-state
output is held at high impedance when not
sending data to the μController. See "C-BUS"
Timing Diagram (Figure 4).
6
CSN
I/P
The "C-BUS" data loading control function: this
input is provided by the μController. Data
transfer sequences are initiated, completed or
aborted by the CSN signal. See "C-BUS" Timing
Diagram (Figure 4).
7
IRQN
O/P
This output indicates an interrupt condition to the
μController by going to a logic "0". This is a
"wire-ORable" output, enabling the connection of
up to 8 peripherals to 1 interrupt port on the
μController. This pin has a low impedance
pulldown to logic "0" when active and a high-
impedance when inactive. An external pullup
resistor is required.
The conditions that cause interrupts are
indicated in the IRQ FLAG register and are
effective if not masked out by a corresponding
bit in the IRQ MASK register.
