Description
L99PM62XP
Doc ID 16363 Rev 2
To prevent the system from a deadlock condition (no wake up possible) a configuration
where the periodic timer interrupt and wake up by LIN and HS CAN are disabled, is not
allowed. The default configuration is entered for all wake-up sources in case of such an
invalid setting.
All wake-up events from V1 standby mode (except IV1 > Icmp) are indicated to the
microcontroller by a low-pulse at RxDL/NINT (duration: 56 s).
Wake-up from V1 standby by SPI Access might be used to check the interrupt service
handler.
2.2.6
Wake-up inputs
The de-bounced digital inputs WU1 to WU3 can be used to wake up the L99PM62XP from
standby modes. These inputs are sensitive to any level transition (positive and negative
edge)
For static contact monitoring, a filter time of 64 s is implemented at WU1-3. The filter is
started when the input voltage passes the specified threshold.
In addition to the continuous sensing (static contact monitoring) at the wake up inputs, a
cyclic sense functionality is implemented. This feature allows periodical activation of the
wake-up inputs to read the status of the external contacts. The periodical activation can be
linked to Timer1 or Timer2 (see Section 2.2.7: Cyclic contact supply ). The input signal is
filtered with a filter time of 16 s after a programmable delay (80 s or 800 s) according to
the configured timer on-time. A wake-up is processed if the status has changed versus the
previous cycle.
The outputs OUT_HS and OUT1-4 can be used to supply the external contacts with the
timer setting according to the cyclic monitoring of the wake-up inputs.
If the wake-up inputs are configured for cyclic sense mode the input filter timing and input
filter delay (WUx_filt in control register 2) must correspond to the setting of the high-side
output which supplies the external contact switches (OUTx in control register 0).
In standby mode, the inputs WU1-3 are SPI configurable for pull-up or pull-down current
source configuration according to the setup of the external. In active mode the inputs have a
pull down resistor.
In active mode, the input status can be read by SPI (Status Register 2). Static sense should
be configured (Control Register 2) before the read operation is started (In cyclic sense
configuration, the input status is updated according to the cyclic sense timing; Therefore,
reading the input status in this mode may not reflect the actual status).
2.2.7
Cyclic contact supply
In V1 standby and VBAT standby modes, any high-side driver output (OUT1..4, OUTHS) can
be used to periodically supply external contacts.
The timing is selectable by SPI
Timer 1: period is Xs. The on-time is 10 ms resp. 20 ms: With X
∈ {1, 2, 3, 4 s}
Timer 2: period is X ms. The on- time is 100 s resp. 1ms: With X
∈ {10, 20, 50, 200 ms}
