22.3.2.13 ECLK Control Register (ECLKCTL)
1
Read: Anytime. In emulation modes, read operations will return the data from the external bus, in all other
modes the data are read from this register.
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.
836
Reset values in emulation modes are identical to those of the target mode.
