- * Register definitions for the Intel 8253 Programmable Interval Timer.
- *
- * This chip has three independent 16-bit down counters that can be
- * read on the fly.  There are three mode registers and three countdown
- * registers.  The countdown registers are addressed directly, via the
- * first three I/O ports.  The three mode registers are accessed via
- * the fourth I/O port, with two bits in the mode byte indicating the
- * register.  (Why are hardware interfaces always so braindead?).
- *
- * To write a value into the countdown register, the mode register
- * is first programmed with a command indicating the which byte of
- * the two byte register is to be modified.  The three possibilities
- * are load msb (TMR_MR_MSB), load lsb (TMR_MR_LSB), or load lsb then
- * msb (TMR_MR_BOTH).
- *
- * To read the current value ("on the fly") from the countdown register,
- * you write a "latch" command into the mode register, then read the stable
- * value from the corresponding I/O port.  For example, you write
- * TMR_MR_LATCH into the corresponding mode register.  Presumably,
- * after doing this, a write operation to the I/O port would result
- * in undefined behavior (but hopefully not fry the chip).
- * Reading in this manner has no side effects.
- *
- * The outputs of the three timers are connected as follows:
- *
- *	 timer 0 -> irq 0
- *	 timer 1 -> dma chan 0 (for dram refresh)
- * 	 timer 2 -> speaker (via keyboard controller)
- *
- * Timer 0 is used to call hardclock.
- * Timer 2 is used to generate console beeps.
