Halt Mode
When the IA88C00 execute the Wait for Interrupt (WFI) instruction and bit 3 of R223 (Halt Mode
register) is cleared, the processor enters HALT mode. The internal CPU clock is disabled, however, the
oscillator remains active. Use of the UART, timers and DMA remains under user control. The Halt mode
is exited via an interrupt or DMA request. The programming model for Halt Mode is detailed in R223
