n 16-bit Timer/Counter Registers
TMCR (16-bit timer control register)
TCR (16-bit timer count register)
Upper bits (TCHR)
Lower bits (TCLR)
R/W: Readable and writable
R : Read-only

n 16-bit Timer/Counter Interrupt source
IRQ6: For both the interval timer and counter functions, the 16-bit timer/counter generates an
