9.1.4

ResetStatus and GlobalReset commands

The ResetStatus command is a specific reset command which acts on all status registers

releasing all the latched flags. The command is executed only when the SD input is low,

otherwise the SPI_ERR flag is forced low.

The GlobalReset command reset all the registers to the default and releases all the failure

flag (if latched). It can be sent when the device is in the configuration mode only, otherwise

the command is ignored and the SPI_ERR flag is forced low.

9.1.5

Sleep command

The command forces the device to switch in standby mode within a tsleep period. The

command is executed only when the SD pin in low, if the SD pin is high the command is

ignored and the SPI_ERR flag is forced low.

Refer to Section 6.4 on page 24 for the description of the standby mode.

9.1.6

NOP command

The command does not modify the device status and does not generate any answer.
