INTMSK register (register 17)
The INTMSK register defines the valid interrupt sources
allowed to assert interrupt request pin. Table-7.17 lists
all the bits of this register.
SPEED register (register 18)
The SPEED register specifies or indicates the speed
rate of each port. It is read-only, unless the bit-12 of
register-25 is set (through POS to disable automatic
PHY management). At read-only mode, it indicates
the speed achieved through PHY management. At the
write-able mode, the control CPU will be able to assign
speed rate for each port. Table-7.18 describes all the
bit of this register.
LINK register (register 19)
The LINK register specifies or indicates the link status
of each port. It is read-only, unless bit-12 of register-
25 is set (through POS, to disable automatic PHY man-
agement). At read-only mode, it indicates the result
achieved by PHY management. At write-able mode,
