- * This include file contains information pertaining to the ERC32.
- * The ERC32 is a custom SPARC V7 implementation based on the Cypress

- * was developed by the European Space Agency to target space applications.
- *
- * NOTE: Other than where absolutely required, this version currently
- * supports only the peripherals and bits used by the basic board
- * support package. This includes at least significant pieces of
- * the following items:
- *
- * + UART Channels A and B
- * + General Purpose Timer
- * + Real Time Clock
- * + Watchdog Timer (so it can be disabled)
- * + Control Register (so powerdown mode can be enabled)
- * + Memory Control Register
- * + Interrupt Control

- * The following macros attempt to hide the fact that the General Purpose
- * Timer and Real Time Clock Timer share the Timer Control Register. Because
- * the Timer Control Register is write only, we must mirror it in software
- * and insure that writes to one timer do not alter the current settings
- * and status of the other timer.
- *
- * This code promotes the view that the two timers are completely independent.
- * By exclusively using the routines below to access the Timer Control
- * Register, the application can view the system as having a General Purpose
- * Timer Control Register and a Real Time Clock Timer Control Register
- * rather than the single shared value.
- *
- * Each logical timer control register is organized as follows:
- *
- * D0 - Counter Reload
- * 1 = reload counter at zero and restart
- * 0 = stop counter at zero
- *
- * D1 - Counter Load
- * 1 = load counter with preset value and restart
- * 0 = no function
- *
- * D2 - Enable
- * 1 = enable counting
- * 0 = hold scaler and counter
- *
- * D3 - Scaler Load
- * 1 = load scalar with preset value and restart
- * 0 = no function
- *
- * To insure the management of the mirror is atomic, we disable interrupts
- * around updates.
