hen the DH needs to update the value of the parameters described
hereafter, it shall send a CORE_RESET_CMD/CORE_INIT_CMD sequence
after the CORE_SET_CONFIG_CMD, to ensure that the new value is used
for the parameters.
If numerous parameters are updated thanks to multiple
CORE_SET_CONFIG_CMD commands, a single CORE_RESET_CMD/
CORE_INIT_CMD sequence is enough after the last
CORE_SET_CONFIG_CMD.
!
An
y CORE_SET_CONFIG_CMD to one of the following parameters or to the
[NCI] standard parameters will trigger an EEPROM write cycle. Since the
PN7150 EEPROM has a limited number of Erase/Write cycles (300 000), it is
highly recommended to only use the CORE_SET_CONFIG_CMD during the
NCI initialization sequence.
