Bit Field Value Description
31-16 Reserved 0 Reads return 0. Writes have no effect.
15-0 HRSHARE
n+1 / n
HR Share Bits
Enables the share of the same pin for two HR structures. For example, if bit HRSHARE1/0 is set,
the pin HET[0] will then be connected to both HR input structures 0 and 1.
Note: If HR share bits are used, pins not connected to HR structures (the odd number pin in each
pair) can be accessed as general inputs/outputs.
0 HR Input of HET[n+1] and HET[n] are not shared.
1 HR Input of HET[n+1] and HET[n] are shared; both measure pin HET[n].
