IR (Interrupt Register)
The /INT signal retain low as long as any unmasked signal is set, and will not go high until all unmasked bits in this Register have been cleared.
Sx_INT
Occurrence of Socket x Socket Interrupt
It is set in case that interrupt occurs at the socket x. This bit will be automatically cleared when Sx_IR is cleared to 0x00.
Sn_IR (Socket n Interrupt Register)
The values are cleared by reading this register. Howerver, it takes 2ms to clear register after reading internally, and you may wait about 2ms after reading this register.
Получается, попав в обработчик прерывания я должен на 2 мс запрещать это прерывание?The /INT signal retain low as long as any unmasked signal is set, and will not go high until all unmasked bits in this Register have been cleared.

Второй вопрос - в примерах передачи количество свободного места мониторится периодическим чтением Sx_TX_FSR. И если места не хватает, то висим в цикле постоянного чтения этого регистра пока предыдущий пакет не уйдет и место не освободится. Правильно ли я понял, что по прерываниям эту операцию не сделать никак?
