Cyclic Mode Configuration Registers (CYCMU)
Cyclic Sense Mode Configuration:
The off time (dead time) in Cyclic Sense Mode is calculated by following formula:
where E1E0 represent the exponent, which can be configured by the register bits
PMU_SLEEP.CYC_SENSE_E01 <1:0>. M3M2M1M0 represent the mantissa configurable by the register bits
PMU_SLEEP.CYC_SENSE_M03. With this setting a time range between
• minimum 2 ms and
• maximum 2048 ms
can be configured. In addition to the off time (dead time) a sample delay for the sensing period can be
configured. The sample delay applies after the corresponding supply (HS/VDDEXT) used in the cyclic mode is
turned on to the sensing window, where the wake inputs (MONx/GPIOx) are sensed. The delay time can be
configured in the PMU_SLEEP.CYC_SENSE_S_DEL register. The sensing window is fixed to typ. 10 us.
Cyclic Wake Mode Configuration:
The off time (dead time) in Cyclic Wake Mode is calculated by following formula:
.
where E1E0 represent the exponent, which can be configured by the register bits PMU_SLEEP.CYC_WAKE_E01
<1:0>. M3M2M1M0 represent the mantissa configurable by the register bits PMU_SLEEP.CYC_WAKE_M03. With
this setting a time range between
• minimum 2 ms and
• maximum 2048 ms
can be configured.
Note:
all timings in the cyclic modes are derived from LP_CLK2. The values used in the register description
are typical values. Their variation is depending on the variation of LP_CLK2.
