The IPCGRH register facilitates interrupts to external hosts. Operation and use of the IPCGRH register is the same as for other IPCGR registers. The interrupt output pulse created by the IPCGRH register appears on device pin HOUT.
The host interrupt output pulse is stretched so that it is asserted for four bootcfg clock cycles (SYSCLK1/6) followed by a deassertion of four bootcfg clock cycles. Generating the pulse results in a pulse-blocking window that is eight SYSCLK1/6-cycles long. Back-to-back writes to the IPCRGH register with the IPCG bit (bit 0) set, generates only one pulse if the back-to-back writes to IPCGRH are less than the eight SYSCLK1/6 cycle window — the pulse blocking window. To generate back-to-back pulses, the back-to-back writes to the IPCGRH register must be written after the eight SYSCLK1/6 cycle pulse-blocking window has elapsed. The IPC Generation Host register is shown in Figure 10-25 and described in Table 10-44.
