7.4 RISC TIMER TABLES
The RISC controller has the ability to control up to 16 timers. These timers are separate from
the four general-purpose timers and baud rate generators in the CPM. The 16 timers are
ideally used in protocols that do not require extreme precision, but in which it is desirable to
off-load the host CPU from having to scan the timer tables that are created in software.
These timers are clocked from an internal timer used only by the RISC.
The features of the RISC timer tables are as follows:
• Up to 16 Timers Supported
• Two Timer Modes: One-Shot and Restart
• Maskable Interrupt on Timer Expiration
• Programmable Timer Resolution As Low As 41 s at 25 MHz
• Maximum Timeout Period of 172 Sec at 25 MHz
