This option places Modbus timer IRQ handler into IRAM.
|
|
This allows to avoid delays related to processing of non-IRAM-safe interrupts
|
|
during a flash write operation (NVS updating a value, or some other
|
|
flash API which has to perform an read/write operation and disable CPU cache).
|
|
This option has dependency with the UART_ISR_IN_IRAM option which places UART interrupt
|
|
handler into IRAM to prevent delays related to processing of UART events.
