This register is used to enable the switching elements and the generation of the
programmable control output signals.
COUTLEN:
The COUTLEN bit enables the generation of the COUTL signal under control
of the left switching element; the switching element that routes between the
DINT and DOUTL buses, or DINB and DOUTL buses, respectively. After
reset, the COUTL signal is forced high, until the COUTLEN bit is set high.
COUTREN:
The COUTREN bit ernables the generation of the COUTR signal under
control of the right switching element; the switching element that routes
between the DINT and DOUTR buses, or DINB and DOUTR buses,
respectively. After reset, the COUTR signal is forced high, until the
COUTREN bit is set high.
SELEN:
The SELEN bit enables operation of the left switching element (the switching
element that routes between the DINT and DOUTL buses, or DINB and
DOUTL buses, respectively). After reset, the left switching element is held
reset to save power, until the SELEN bit is set high.
SEREN:
The SEREN bit enables operation of the right switching element (the
