Description
31
SRCOMP_V Override Enable—R/W.
0 = SM Rcomp is active for vertically oriented buffers (Default).
1 = SM Rcomp is NOT-active for vertically oriented buffers.

SRCOMP_VP—RO or R/W.
P-Channel Compensation Value for Vertical Buffers. This value is
generated by the Rcomp logic to control the drive characteristics of the vertically oriented P-channel
devices in the SM buffers.
In
Normal operation
, field is read-only and reflects current compensation.
In
Override Mode
(see bit 31), field is written with desired compensation value which is loaded via
software when SM Rcomp operation is disabled.

SRCOMP_VN—RO or R/W.
N-Channel Compensation Value for Vertical Buffers. This value is
generated by the Rcomp logic to control the drive characteristics of the vertically oriented N-channel
devices in the SM buffers.
In
Normal operation
, field is read-only and reflects current compensation.
In
Override Mode
(see bit 31), field is written with desired compensation value which is loaded via
software when SM Rcomp operation is disabled.
15
SRCOMP_H Override Enable—R/W.
0 = SM Rcomp is active for horizontally oriented buffers (Default).
1 = SM Rcomp is NOT-active for horizontally oriented buffers.
