Note:
Interrupt Edge Select Register 1 (IEGR1)
IEGR1 is an 8-bit read/write register used to designate whether pins IRQ
edge sensing or falling edge sensing. Upon reset, IEGR1 is initialized to H'70.
Bit 7 Reserved Bit: Bit 7 is reserved: it is always read as 0 and cannot be modified.
Bits 6 to 4 Reserved Bits: Bits 6 to 4 are reserved; they are always read as 1, and cannot be
modified.
