Table 23-48. Loop Back Pair Select Register (HETLBPSEL) Field Descriptions
Bit Field Value Description
31-16 LBPTYPE
n+1 / n
Loop Back Pair Type Select Bits
These bits are valid only when Loopback mode is enabled (HETLBPDIR[19:16] = 1010).
0 Digital loopback is selected for HR structures on pins HET[n+1] and HET[n].
1 Analog loopback is selected for HR structures on pins HET[n+1] and HET[n].
15-0 LBPSEL
n+1 / n
Loop Back Pair Select Bits
These bits are valid only when Loopback mode is enabled (HETLBPDIR[19:16] = 1010).
If bit x is set, the HR structures on pins HET[n+1] and HET[n] are connected in a loop back mode. The
direction is given by LBPDIR n+1/n and type is selected by LBPTYPE n+1/n.
The pin which is not driven by the N2HET pin actions can still be used as normal GIO pin.
