Bit [7:4]: Reserved
Bit [3:0]: Prog Internal Timer [11:8]
This register holds the high-order nibble of the 12-bit programmable interval timer. Reading this register returns the high-order
nibble of the 12-bit timer at the instant that the low-order byte was last read
Bit [7:0]: Prog Interval [7:0]
This register holds the lower 8 bits of the timer. While writing into the 12-bit reload register, write lower byte first then the higher nibble
Bit [7:4]: Reserved
Bit [3:0]: Prog Interval [11:8]
This register holds the higher 4 bits of the timer. While writing into the 12-bit reload register, write lower byte first then the higher nibble
