INTSTS (PHY INTERRUPT STATUS REGISTER, 0x227E)
This register is used to indicate the kinds of the interrupt when the multiple interrupts occur.
INTCON (PHY INTERRUPT CONTROL REGISTER, 0x2277)
This register is used to mask off the interrupt of a modem block
INTIDX (PHY INTERRUPT STATUS AND INDEX REGISTER, 0x2278)
This register is used to indicate the kinds of the interrupt when it occurs

Reserved
RXEND_INT Interrupt Mask. This field masks RXEND_INT off. When
RXENDMSK field is set to ‘0’, RXEND_INT interrupt is not generated.
This interrupt should be used to support the successful packet reception.
RXSTART_INT Interrupt Mask. This field masks RXEND_START off.
When RXSTMSK field is set to ‘0’, RXSTART_INT interrupt is not
generated. RXSTART_INT is not a mandatory interrupt. It is
recommended to mask off RXSTART_INT interrupt when the rapid
packet reception is needed.
TXEND_INT Interrupt Mask. This field masks TXEND_INT off. When
TXENDMSK field is set to ‘0’, TXEND_INT interrupt is not generated.
This interrupt should be used to support the successful packet
transmission.
MDREADY_INT Interrupt Mask. This field masks MDRDY_INT off.
When MRDYMSK field is set to ‘0’, MDRDY_INT interrupt is not
generated. This interrupt should be used to check whether a modem
block is ready for transmission /reception or not.
Reserved
Reception of Extended Transfer Rate Packet. Indicates the data rate
of the received packet when an RXEND_INT interrupt occurs. When
FRMDX field is set to ‘0’ and RXRATE field in RXFRM1 register is ‘1’, it
indicates a packet reception data rate of 500kbps. When RXRATE field
is ‘2’, it indicates the packet reception data rate of 1Mbps.
All Interrupt Clear. Disables all interrupts when they occur. This field
clears all interrupts occurred.
When multiple interrupts occur at the same time, the modem block
stores them in a buffer and processes them in order. When INTIDX field
is read, the executed interrupts are cleared in order. When ALLINTCLR
field is set to ‘0’, all the interrupts in buffer are cleared at the same time.
Reserved
Interrupt Table Index. Shows the kind of the interrupt when an
interrupt occurs, in order if multiple interrupts occur simultaneously. The
INTSTS field in the INTSTS register should be used for looking through
a list of all interrupts that have been triggered. After reading INTIDX
field, executed interrupts are cleared automatically.
Reserved
Reception of Extended Transfer Rate Packet. This field is equal to
the FRMDX field in the INTIDX register.
