Hold Operation
The hold operation is used to pause serial communications without setting the device in the non-select status. In the
hold status, the serial data output goes in high impedance, and both of the serial data input and the serial clock go in
“Don’t care”. Be sure to set the chip select ( CS ) to “L” to set the device in the select status during the hold status.
Generally, during the hold status, the device holds the select status. But if setting the device in the non-select status, the
users can finish the operation even in progress.
Figure 17 shows the hold operation. Set Hold ( HOLD ) to “L” when the serial clock (SCK) is in “L”, Hold ( HOLD ) is
switched at the same time the hold status starts. If setting Hold ( HOLD ) to “H”, Hold ( HOLD ) is switched at the same
time the hold status ends.
Set Hold ( HOLD ) to “L” when the serial clock (SCK) is in “H”; the hold status starts when the serial clock goes in “L”
after Hold ( HOLD ) is switched. If setting Hold ( HOLD ) to “H”, the hold status ends when the serial clock goes in “L”
after Hold ( HOLD ) is switched.
