The 64 registers in address range 0x240-0x29E serve as a data bank organized
as three pages, each with 32 32-bit words. Those registers are used to hold the
return value from the command. The value of cmd_read_data_page_select
determines which page is currently accessible.
See Table 16 for the details.

corresponding to a tx link. A logic ‘0’ means
there is not interrupt condition on the link, while
a logic ‘1’ means interrupt condition exists on
the link.
