Programming the Peripherals
contents of the internal X I/O memory space are listed in Appendix B, Programming Reference,
Table B-2.
5.3 Reading Status Registers
Each peripheral has a read-only status register that indicate the state of the peripheral at a given
time. The HI08, ESSI, and SCI have dedicated status registers. The triple timer has status bits
embedded within a control/status register. Changes in the status bits can generate interrupt
conditions. For example, the HI08 has a host status register with two host flag bits that can be
encoded by the host to generate an interrupt in the DSP.
