There are two monitoring pins on the Basis board:
BLDC Motor Control Kit with ATA6833/ATA6834
• For investigations, Watchdog can be disabled by setting the WDD Jumper to ON
• VCC voltage should be set via VMODE jumper to 5V mode by connection VMODE - VINT
• At normal function, the Reset pin is always on high level. Otherwise some failures may
• At CPout, the charge pump voltage is measurable. The charge pump voltage level U
