Configuration Registers
The configuration of the
EM2420
is done by
programming the 16-bit configuration
registers. Complete descriptions of the
registers are given in the following tables.
After chip reset (from the
RESETn
pin or
programmable through the
MAIN.RESETn
configuration bit), all the registers have
default values as shown in the tables.
Note that the
MAIN
register is only reset
by using the pin reset
RESETn
. When
writing to this register, all bits will get the
value written, not the default value. This
also means that the
MAIN.RESETn
bit
must be written both low and then high to
perform a chip reset through the serial
interface.
15
Registers, listed first in Table 11 below.
Accessing these registers will initiate the
change of an internal state or mode. There
are 33 normal 16-bits registers, also listed
registers
are
Strobe
Command
in Table 11. Many of these registers are
for test purposes only, and need not be
accessed for normal operation of the
EM2420
.
The FIFOs are accessed through two 8-bit
registers,
TXFIFO
and
RXFIFO
. The
TXFIFO
register is write only. Data may
still be read out of the TXFIFO through
regular RAM access (see section RAM
access section on page 27), but data is
then not removed from the FIFO. Note that
the crystal oscillator must be active for all
FIFO and RAM access.
During the address transfer and while
writing to the TXFIFO, a status byte is
returned on the serial data output pin
SO
.
This status byte is described in Table 5 on
page 27.
All configuration and status registers are
described in the tables following Table 11.
Address
