HIGH PERFORMANCE DUAL PCI EXPRESS UART
REGA [15:8] Register
Reserved.
TIMERCNTL [7:0] Register
The bits [3:0] of this register are used to issue commands. The commands are self-clearing, so reading this
register does not show the last written command. Reading this register returns a value of 0x01 when the Timer
interrupt is enabled and there is a pending Timer interrupt. It returns a value of 0x00 at all other times. The
default settings of the Timer, upon power-up, a hardware reset or upon the issue of a ’Timer Reset’ command
are:
Timer Interrupt Disabled
Re-triggerable mode selected
Internal 125MHz clock selected as clock source
Timer output not routed to MPIO[0]
Timer stopped
TABLE 9: TIMER CONTROL REGISTERS
TIMERCNTL [7:4] Reserved
TIMERCNTL [3:0] These bits are used to invoke a series of commands that control the function of the Timer/Counter.
The commands 1100 to 1111 are reserved.
0001: Enable Timer Interrupt
0010: Disable Timer Interrupt
0011: Select One-shot mode
0100: Select Re-triggerable mode
0101: Select Internal 125MHz clock as clock input for the Timer
0110: Select External Clock input through the TMRCK pin for the Timer
0111: Route Timer output to MPIO[0] pin
1000: De-route Timer output from MPIO[0]
1001: Start Timer
1010: Stop Timer
1011: Reset Timer
