Chapter 23 DQ256 Port Integration Module (S12XDQ256PIMV2)
23.0.5.13 ECLK Control Register (ECLKCTL)
Read: Anytime. In emulation modes, read operations will return the data from the external bus, in all other
modes the data source is depending on the data direction value.
Write: Anytime. In emulation modes, write operations will also be directed to the external bus.
The ECLKCTL register is used to control the availability of the free-running clocks and the free-running
clock divider.

No ECLK — This bit controls the availability of a free-running clock on the ECLK pin. Clock output is always
active in emulation modes and if enabled in all other operating modes.
