Bit 6 (UERRIF) :
UART Receiving Error Interrupt, cleared by software or UART
disabled.
Bit 5 (RBFF) :
UART Receive Mode Data Buffer Full Interrupt Flag. Flag cleared
by software.
Bit 4 (TBEF) :
UART Transmit Mode Data Buffer Empty Interrupt Flag. Flag
cleared by software.
Bit 3 (TBIF) :
Time Base Timer Interrupt Flag. Flag cleared by software.
Bit 2 (EXIF1) :
External Interrupt Flag (INT1). Flag cleared by software.
Bit 0 (TCIF0) :
TCC Overflow Interrupt Flag. Set as TCC overflows; flag cleared
by software.
"1" means interrupt request, "0" means non-interrupt
ISFR2 can be cleared by instruction, but cannot be set by instruction
IMR2 is the interrupt mask register
Note that reading ISFR2 will obtain the result of the ISFR2 "logic AND" and
