eMIOS200 Counter Register (EMIOS_CCNTR[n])
The EMIOS_CCNTR[n] register contains the value of the internal counter. When GPIO mode is selected
or the channel is frozen, the EMIOS_CCNTR[n] register is read/write. For all other modes, the
EMIOS_CCNTR[n] is a read-only register. When entering some operation modes, this register is
automatically cleared (refer to
Section 26.5.1.1, “Unified Channel Modes of Operation
Depending on the channel configuration it may have an internal counter or not. It means that if at least one
mode that requires the counter is implemented, then the counter is present, otherwise it is absent.
26.4.8
eMIOS200 Control Register (EMIOS_CCR[n])
The control register gathers bits reflecting the status of the unified channel input/output signals and the
overflow condition of the internal counter, as well as several read/write control bits.
