4.11.8 Auto-increment Read/Write Access

Auto-increment read/write access timing for the GSPI interface is shown in Figure 4-16

to Figure 4-20.

Auto-increment mode is enabled by the setting of the AUTOINC bit of the Command

Word.

In this mode, multiple Data Words can be read from/written to the device using only one

starting address. Each access is initiated by a high-to-low transition of the CS pin, and

consists of a Command Word and one or more Data Words. The internal address is

automatically incremented after the first read or write Data Word, and continues to

increment until the read or write access is terminated by a low-to-high transition of the

CS pin.

Note: Writing to HOST_CONFIG using Auto-increment access is not allowed.

The maximum interface clock rate is 27MHz and the inter-command delay time

indicated in the diagram as tcmd, is a minimum of 4 SCLK clock cycles.

For read access, the time from the last bit of the first Command Word to the start of the

data output of the first Data Word as defined by t5, will be no less than 5 SCLK cycles at

27MHz. All subsequent read data accesses will not be subject to this delay during an

Auto-Increment read.
