Offset:
• WDCLKS: Clock Selection
• HPCV: High Preload Counter Value (Code Label WD_HPCV)
Counter is preloaded when watchdog counter is restarted with bits 0 to 11 set (FFF) and bits 12 to 15 equaling HPCV.
• CKEY: Clock Access Key (Code Label WD_CKEY)
Used only when writing WD_CMR. CKEY is read as 0.
0x06E: Write access in WD_CMR is allowed.
Other value: Write access in WD_CMR is prohibited.
