5.1 Introduction
The SX8634 configuration parameters are taken from the QSM or the NVM and loaded into the SPM as explained
in the chapter ‘functional description’.
This chapter describes the details of the configuration parameters of the SX8634.
.
The SPM is split by functionality into 6 configuration sections:
The total address space of the SPM and the NVM is 128 bytes, from address 0x00 to address 0x7F.
Two types of memory addresses, data are accessible to the user.
• ‘application data’: Application dependent data that need to be configured by the user.
• ‘reserved’: Data that need to be maintained by the user to the QSM default values (i.e. when NVM is burned).
The Table 12 and Table 13 resume the complete SPM address space and show the ‘application data’ and
‘reserved’ addresses, the functional split and the default values (loaded from the QSM).
Revision 7_6, October 10
• General section: operating modes,
• Capacitive Sensors section: related to lower level capacitive sensing,
• Button: related to the conversion from sensor data towards button information,
• Slider: related to the conversion from sensor data towards slider information,
• Mapping: related to mapping of button and slider information towards wake-up and GPIO pins,
