3.5.29 Start logic edge control register 0
3.5.30 Start logic signal enable register 0
Table 35.
Note: If the NMISRC register is used to select an interrupt as the source of Non-Maskable
interrupts, and the selected interrupt is enabled, one interrupt request can result in both a
Non-Maskable and a normal interrupt. Avoid this situation by disabling the normal
interrupt in the NVIC, as described in
The STARTAPRP0 register controls the start logic inputs of ports 0 (PIO0_0 to PIO0_11)
and 1 (PIO1_0). This register selects a falling or rising edge on the corresponding PIO
input to produce a falling or rising clock edge, respectively, for the start logic (see
Section
Every bit in the STARTAPRP0 register controls one port input and is connected to one
wake-up interrupt in the NVIC. Bit 0 in the STARTAPRP0 register corresponds to interrupt
0, bit 1 to interrupt 1, etc. (see
Remark: Each interrupt connected to a start logic input must be enabled in the NVIC if the
corresponding PIO pin is used to wake up the chip from Deep-sleep mode.
