This register is used in pattern detecting application. If this function is disabled (IOCE[2] = 0),
the PDA function is disabled. RB register is also used as a general-purpose register.

IOC9[3&7] Undefined register. The default value is Zero.
The PDA includes an enable control bit, an input pin (P60), a prescaler, a Pattern Detecting
block, two special register (RA and RB), and two interrupts (high pattern counter interrupt
and low pattern counter interrupt).
To use this function, the enable control bit, IOCE[2] has to be set first. Otherwise the P60
will just be treated as an input only pin and the RA/RB as general purpose register.
As long as the IOCE[2] control bit is set to 1 and the P60 is set as input pin, the Pattern
