31-p
~ 6 bit shift count at 20,22:26 encoded as 63-~.
P 5 bit bit position at 26
+ q 6 bit bit position at 20,22:26
T 5 bit field length at 31 (encoded as 32-T)
+ % 6 bit field length at 23,27:31 (variable extract/deposit)
+ | 6 bit field length at 19,27:31 (fixed extract/deposit)
A 13 bit immediate at 18 (to support the BREAK instruction)
^ like b, but describes a control register
