0:
01 HPRCOM configured as differential of HPLCOM
1:
10 HPRCOM configured as external feedback with HPLCOM as constant VCM output
0:
101 – 111: Reserved. Do not write these sequences to these register bits.
D2 R/W 0 Short-Circuit Protection Control
0: Short-circuit protection on all high-power output drivers is disabled.
1: Short-circuit protection on all high-power output drivers is enabled.
D1 R/W 0 Short-Circuit Protection Mode Control
0: If short-circuit protection is enabled, it limits the maximum current to the load.
1: If short-circuit protection is enabled, it powers down the output driver automatically when a short is
detected.
D0 R 0 Reserved. Write only zero to this register bit.
Page 0/Register 39: Reserved Register
