MAX19527 Evaluation Kit
Refer to the System Timing Requirements section in the
MAX19527 IC data sheet for additional information for
configuring the Data, FRAME, and CLKOUT test levels.
The Power_ Management group box contains two sets
of controls. The first set is used only when the SHDN
pin on the EV kit is set low and the second set is used
only when the SHDN pin on the EV kit is set high. When
checked, the IN1_Active–IN8_Active checkboxes enable
the input channel, or disable the input channel when left
unchecked. The Sleep/Nap_ Mode checkbox toggles
between nap mode when checked and sleep mode
when unchecked, as long as the IN1_Active–IN8_Active_
checkboxes are left unchecked. The Enable_ All and
Disable_All buttons are available to enable and disable
all input channels simultaneously. For more details on
power management, refer to the MAX19527 IC data
sheet.

A serial interface can be used by advanced users by
selecting the Options_ |_ Interface_ (Advanced_ Users)_
menu item. Custom bit-banging firmware commands are
used to implement a bidirectional SPI interface. Read
addresses always begin with 0x8_ and write addresses
always begin with 0x0_.
For writing to registers, click on the Connection tab
(Figure 3). Enter the raw command bytes value of
0x77_0x05_0xA0_0xA0 (where 0x05 is the register write
address in hexadecimal, and 0xA0, 0xA0 are the data in
this example), then press the Send_raw_command_bytes_
button. Note that the custom firmware uses data transfer
of two bytes.
For reading registers, enter the raw command bytes
value of 0x72_ 0x85 (where 0x85 is the register read
address in hexadecimal), then press the Send_ raw
command_ bytes button. The register address and
content are displayed as the first and second byte of
data listed under the Returned_ data_ [hexadecimal]
label, respectively (Figure 4).
