interrupt is noticed from ETHERC1 to the IRC interrupt number 5 internal of a chip. The external pin
INT[3] is used when ETHERC1 is used for the purpose other than an interrupt. This is the same as for
the interrupt number 6. Refer to “3.3 Pin multiplexed” for muliplexed pins.
The TX4937 has as interrupt sources interrupts from 18 types of on-chip peripheral circuits and 6
Table 15.3.1 lists the interrupt sources. Signals with the lower interrupt number have the higher
The interrupt number 5 is shared between INT[3] and ETHERC1. When ETHERC1 is used, an
