26.3.2.2.5 Error Interrupt Enable Set / Reset (EIES/EIER)
The settings in the error interrupt enable register determine which status changes in the error interrupt
register will result in an interrupt. The enable bits are set by writing to EIES (address 30h) and reset by
writing to EIER (address 34h). Writing 1 sets or resets the specific enable bit, writing 0 has no effect.
Figure 26-121 and Table 26-100 illustrate this register.
