RX_USER0_CHGE

Writing a ‘1’ to the RX_OUSER0_CHGE bit enables the generation of an interrupt on a

change of state from a ‘0’ to a ‘1’ of received message header bit RX_USER[0].

RX_PAGE_CHGE[1:0]

Writing a ‘1’ to the RX_PAGE_CHGE[n] bit enables the generation of an interrupt on a

change of state of the received PAGE bits. The RX_PAGE bits that changed value are

indicated by a ‘1’ in the corresponding RX_PAGE_CHGI[n].

RX_LINK_CHGE

Writing a ‘1’ to the RX_LINK_CHGE bit enables the generation of an interrupt on a change

of state of the received LINK bits. When either of the received LINK bits has changed value

the RX_LINK_CHGI bit will be set to a ‘1’.

If the RXFIFO level had reached the threshold value an interrupt will be generated if this bit

is ‘1’. To disable set to ‘0’.

RX_OVFLWE

Writing a ‘1’ to the RX_OVFLWE bit enables the generation of an interrupt when

RX_OVFLWI is a ‘1’.

RX_THRSHLDE

Writing a ‘1’ to the RX_THRSHLDE bit enables the generation of an interrupt when

RX_THRSHLDI is a ‘1’
