BITS DESCRIPTIONS
[0] RXINTR
The Receive Interrupt indicates the Rx interrupt status.
If RXINTR high and its corresponding enable bit, EnRXINTR of
MISTA register, is also high indicates the EMC generates Rx
interrupt to CPU. If RXINTR is high but EnRXINTR of MISTA is
disabled, no Rx interrupt is generated.
The RXINTR is logic OR result of the bits 1~14 in MISTA register
do logic AND with the corresponding bits in MIEN register. In
other words, if one of the bits 1~14 in MISTA register is high and
its corresponding enable bit in MIEN register is also enabled, the
RXINTR will be high.
Because the RXINTR is a logic OR result, clears bits 1~14 of
MISTA register makes RXINTR be cleared, too.
1’b0: No status of bits 1~14 in MISTA is set or no enable of bits
1~14 in MIEN is turned on.
1’b1: At least one status of bits 1~14 in MISTA is set and its
corresponding enable bit is turned on.
MAC General Status Register (MGSTA)
The MGSTA also keeps the statuses of EMC. But the statuses in the MGSTA will not trigger any
interrupt. The MGSTA is a write clear register and write 1 to corresponding bit clears the status.
