HSPI device configuration register 4

Fields

REFRESH

Refresh rate This field enables the refresh rate feature. The nCS is released every REFRESH+1 clock cycles for writes, and REFRESH+4 clock cycles for reads. Note: These two values can be extended with few clock cycles when refresh occurs during a byte transmission in single, dual or quad mode, because the byte transmission must be completed. others: Maximum communication length is set to REFRESH+1 clock cycles.

0 (B_0x0): Refresh disabled
