Description
Prevents sampling of pin PIO0_1 for entering ISP mode. PIO0_1 is
available for other uses.
Access to chip via the SWD pins is disabled. This mode allows partial
flash update using the following ISP commands and restrictions:
This mode is useful when CRP is required and flash field updates are
needed but all sectors can not be erased. Since compare command
is disabled in case of partial updates the secondary loader should
implement checksum mechanism to verify the integrity of the flash.
Access to chip via the SWD pins is disabled. The following ISP
commands are disabled:
When CRP2 is enabled the ISP erase command only allows erasure
of all user sectors.
Access to chip via the SWD pins is disabled. ISP entry by pulling
PIO0_1 LOW is disabled if a valid user code is present in flash sector
0.
This mode effectively disables ISP override using PIO0_1 pin. It is up
to the user’s application to provide a flash update mechanism using
IAP calls or call reinvoke ISP command to enable flash update via
UART.
Caution: If CRP3 is selected, no future factory testing can be
performed on the device.
