System Initialization
When power to the CS5525/26 is applied, they are
held in a reset condition until their 32.768 kHz os-
cillators have started and their start-up counter-tim-
er elapses. Due to the high Q of a 32.768 kHz
crystal, the oscillators take 400-600 ms to start. The
converter’s counter-timer counts no more than
1024 oscillator clock cycles to make sure the oscil-
lator is fully stable. During this time-out period the
serial port logic is reset and the RV (Reset Valid)
bit in the configuration register is set. A reset can be
initiated at any time by writing a logic 1 to the RS
(Reset System) bit in the configuration register.
This automatically sets the RV bit until the RS bit
is written to logic 0, and the configuration register
is read. After a reset, the on-chip registers are ini-
tialized to the following states and the converters
are ready to perform conversions.
Command Operation
The CS5525/26 include a microcontroller with five
registers used to control the converter. Each regis-
ter is 24-bits in length except the 8-bit command
register (command, configuration, offset, gain, and
conversion data). After a system initialization or re-
set, the serial port is initialized to the command
mode and the converter stays in this mode until a
valid 8-bit command is received (the first 8-bits
into the serial port). Table 1 lists all the valid com-
mands. Once a valid 8-bit command (a read or a
write command word) is received and interpreted
by the command register, the serial port enters the
data mode. In data mode the next 24 serial clock
pulses shift data either into or out of the serial port
(72 serial clock pulses are needed if set-up register
is selected). See Table 2 for configuring the
CS5525/26.
