2.2.6Dual Programmable Timers

The processor provides two independent 32-bit timers, with four programmable clock rates. The user configures the timers through the Timer Unit registers. These registers are memory-mapped within the 80960Hx, addressable on 32-bit boundaries. The timers have a single-shot mode and auto-reload capabilities for continuous operation. Each timer has an independent interrupt request to the processor’s interrupt controller.

2.2.7Processor Self Test

When a system error is detected, the FAIL pin is asserted, a fail code message is driven onto the address bus, and the processor stops execution at the point of failure. The only way to resume normal operation is to perform a RESET operation. Because System Error generation may occur sometime after the bus confidence test and even after initialization during normal processor operation, the FAIL pin is HIGH (logic “ 1” ) before the detection of a System Error.

The processor uses only one read bus-transaction to signal the fail code message; the address of the bus transaction is the fail code itself. The fail code is of the form: 0xfeffffnn; bits 6 to 0 contain a mask recording the possible failures. Bit 7, when set to 1, indicates that the mask contains failures from the internal Built-In Self-Test (BIST); when 0, the mask indicates other failures.

Ignore reserved bits 0 and 1. Also ignore bits 5 and 6 when bit 7 is clear (=0).

The mask is shown in Table 2 and Table 3.
