Bits
Name
Description
0:2
SH_TCAN[2:0]
Short TouCAN modules. These three bits determine which TouCAN modules are inter-
nally shorted. See
for a description of the effects of these bit settings.
3:4
SH_TPU[1:0]
Short TPU3 modules. The channels A_TPUCH0 and B_TPUCH0 can be internally
shorted by the SH_TPU0. Channels A_TPUCH1 and B_TPUCH1 can be internally
shorted by SH_TPU1. The effect of the internal shorts depends on the input/output en-
able control for the TPU channels themselves. See
for more information on
bit settings for TPU shorting.

SH_ET1
Short ETRIG1. This bit enables an internal short between ETRIG1 and A_TPUCH15.
0 Short disabled
1 Short ETRIG1 to A_TPUCH15 enabled
7
SH_ET2
Short ETRIG2. This bit enables an internal short between ETRIG2 and B_TPUCH15.
0 Short disabled
1 Short ETRIG2 to B_TPUCH15 enabled
8
SH_T2CLK
Short T2CLK. This bit enables a short between A_T2CLK and B_T2CLK.
0 Short disabled
1 Short A_T2CLK and B_T2CLK enabled. A_T2CLK then takes the input clock.
