Interrupts
The MCC/RTC interrupt event generates an interrupt if the OIE bit of the MCCSR register is
set and the interrupt mask in the CC register is not active (RIM instruction).
Table 38.
1. The MCC/RTC interrupt wakes up the MCU from Active Halt mode, not from Halt mode.

Main Clock Out selection
This bit enables the MCO alternate function on the PF0 I/O port. It is set and
cleared by software.
0: MCO alternate function disabled (I/O pin free for general-purpose I/O).
1: MCO alternate function enabled (f
Note: To reduce power consumption, the MCO function is not active in Active Halt
mode.

No effect on MCC/RTC peripheral. MCC/RTC interrupt causes the device to exit
from Wait mode.
No effect on MCC/RTC counter (OIE bit is set), the registers are frozen.
MCC/RTC interrupt causes the device to exit from Active Halt mode.
MCC/RTC counter and registers are frozen. MCC/RTC operation resumes when
the MCU is woken up by an interrupt with Exit from Halt capability.
