Field
MCKO_DIV
Description
MCKO Division Factor. The value of this signal determines the frequency of MCKO relative to the
system clock frequency when MCKO_EN is asserted. In this table, SYS_CLK represents the
system clock frequency.

EVT_EN
EVTO/EVTI Enable. This bit enables the EVTO/EVTI port functions.
0 EVTO/EVTI port disabled.
1 EVTO/EVTI port enabled.
LP_DBG_EN
Low Power Debug Enable. The LP_DBG_EN bit enables debug functionality to support entry and
exit from low power sleep and stop modes.
0 Low power debug disabled.
1 Low power debug enabled.
SLEEP_SYNC
Sleep Mode Synchronization. The SLEEP_SYNC bit is used to synchronize the entry into sleep
mode between the device and debug tool. The device sets this bit before a pending entry into
sleep mode. After reading SLEEP_SYNC as set, the debug tool then clears SLEEP_SYNC to
acknowledge to the device that it may enter into sleep mode.
0 Sleep mode entry acknowledge.
1 Sleep mode entry pending.
STOP_SYNC
Stop Mode Synchronization. The STOP_SYNC bit is used to synchronize the entry into stop
mode between the device and debug tool. The device sets this bit before a pending entry into stop
mode. After reading STOP_SYNC as set, the debug tool then clears STOP_SYNC to
acknowledge to the device that it may enter into stop mode.
0 Stop mode entry acknowledge.
1 Stop mode entry pending
PSTAT_EN Processor Status Mode Enable.
26.6.2.3 Development Control Register 1, 2 (DC1, DC2)
The development control registers are used to control the basic development features of the Nexus module.
Figure 26-5 shows development control register 1 and Table 26-5 describes the register’s fields.
