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. - */ - -/* - * Frequency of all three count-down timers; (TIMER_FREQ/freq) is the - * appropriate count to generate a frequency of freq hz. - */ -#ifndef TIMER_FREQ -#define TIMER_FREQ 1193182 -#endif -#define TIMER_DIV(x) ((TIMER_FREQ+(x)/2)/(x)) - -/* - * Macros for specifying values to be written into a mode register. - */ -#define TIMER_CNTR0 0 /* timer 0 counter port */ -#define TIMER_CNTR1 1 /* timer 1 counter port */ -#define TIMER_CNTR2 2 /* timer 2 counter port */ -#define TIMER_MODE 3 /* timer mode port */ -#define TIMER_SEL0 0x00 /* select counter 0 */ -#define TIMER_SEL1 0x40 /* select counter 1 */ -#define TIMER_SEL2 0x80 /* select counter 2 */ -#define TIMER_INTTC 0x00 /* mode 0, intr on terminal cnt */ -#define TIMER_ONESHOT 0x02 /* mode 1, one shot */ -#define TIMER_RATEGEN 0x04 /* mode 2, rate generator */ -#define TIMER_SQWAVE 0x06 /* mode 3, square wave */ -#define TIMER_SWSTROBE 0x08 /* mode 4, s/w triggered strobe */ -#define TIMER_HWSTROBE 0x0a /* mode 5, h/w triggered strobe */ -#define TIMER_LATCH 0x00 /* latch counter for reading */ -#define TIMER_LSB 0x10 /* r/w counter LSB */ -#define TIMER_MSB 0x20 /* r/w counter MSB */ -#define TIMER_16BIT 0x30 /* r/w counter 16 bits, LSB first */ -#define TIMER_BCD 0x01 /* count in BCD */ - |
