1b = Interrupt pin asserted is forced.
0b = Normal operation.
000b = No pulse stretching.
001b = 21 ms to 42 ms.
010b = 42 ms to 84 ms.
011b = 84 ms to 170 ms.
100b = 170 ms to 340 ms.
101b = 340 ms to 670 ms.
110b = 670 ms to 1.3 s.
111b = 1.3 s to 2.7 s
After a hardware reset, this bit takes on the value of
pd_config_intpol_a.
0b = jt_int_s active high.
1b = jt_int_a active low
000b = 42 ms.
001b = 84 ms.

011b = 340 ms.
100b = 670 ms.
101b to 111b = Reserved.
After a hardware reset, this bit is a function of
pd_config_led_a[1:0].
00b = 001b.
01b = 000b.
10b = 001b.
11b = 001b.
Reserved, set to 0x0.
