Note:
*PBR.n = 1, enable HALT or STOP mode released by input falling edge signal;
PBR.n = 0, disable HALT or STOP mode release, where n = 6 ~ 0.
*Setting PBR.n register as “1” can enable to release HALT or STOP mode by PB port input signal
from high to low. After HALT or STOP mode released, the oscillator will oscillate at the same time.
If PBINT=1, PB-interrupt subroutine will start. If PBINT=0, the program counter will execute the
next instruction after HALT or STOP.
PBIO register: control PB port as input or output mode. Also, it can be set as partial bits in input mode
and partial bits in output mode.

Note:
*When PBIO corresponding bit is optioned as output mode (PBIO.n=0), PBMD.n will work as
CMOS or NMOS option bit.
(PBIO.n=0, PB.n works as output mode)
PBMD.n = 0, PB.n is NMOS output.
PBMD.n = 1, PB.n is CMOS output.
*When PBIO corresponding bit is optioned as input mode (PBIO.n=1), PBMD.n will work as
internal pull-up resistor enable bit or disable bit.
(PBIO.n=1, PB.n works as input mode)
PBMD.n = 0, disable PB.n internal pull-up resistor,
PBMD.n = 1, enable PB.n internal pull-up resistor.
That n = 6 ~ 0.
