 Please note that the ISR is disabled during flash operation by default. To keep sending transactions during flash operations, enable :ref:`CONFIG_SPI_MASTER_ISR_IN_IRAM` and set :c:macro:`ESP_INTR_FLAG_IRAM` in the member :cpp:member:`spi_bus_config_t::intr_flags`. In this case, all the transactions queued before starting flash operations are handled by the ISR in parallel. Also note that the callback of each Device and their ``callee`` functions should be in IRAM, or your callback will crash due to cache missing. For more details, see :ref:`iram-safe-interrupt-handlers`.

+    -------------

+    .. only:: esp32h2
+
+        This feature is supported only on chip revision v1.2 or later.
+
+    To accommodate the timing requirements of different slave devices and improve signal stability, GP-SPI controllers support two sampling modes when receiving data: Sample Phase 0 and Sample Phase 1. These can be configured via :cpp:member:`spi_device_interface_config_t::sample_point`.
+
+    Sample Phase 0 (SPI mode 0):
+
+    .. wavedrom:: /../_static/diagrams/spi/spi_mode0_delay.json
+
+    Sample Phase 1 (SPI mode 0):
+
+    .. wavedrom:: /../_static/diagrams/spi/spi_mode0_std.json
+
+    By default, the driver uses sample phase 0, when the slave device adheres to standard SPI timing specifications, sample phase 0 provides more stable data reception at high clock frequencies.
