Section 7 Clock Generation

CLMAnCTL1 – CLMAn Control Register 1
This register specifies the signal to be output when the frequency of the clock
signal being monitored (CLMAnTMON) is beyond the specified range.
For details, refer to Section 7.8.4, (2) Indication of Abnormal Clock Frequency.
Access
This register can be read/written in 1- or 8-bit units. It can only be written when
CLMAn is disabled (CLMAnCTL0.CLMAnCLME = 0).
Address
<CLMAn_base> + 04

Initial value

This register is initialized by a reset from any source.
Caution
When the Internal OSC is halted, an internal reset is not generated.
Even when the CLMA2CTL1.CLMA2OSEL bit is set to 0 (reset request signal),
SGA detects the halt of the Internal OSC and the ERROROUT pin outputs the
low level.
