1.1 TICS Pro Status Page

The LMK devices contain live status registers, which are self-clearing, and interrupt (sticky) status registers, which must be cleared by the user. Enable the global interrupt register by configuring the register as shown in Table 1-1. Clear the interrupt status bit by writing a 0 to the same interrupt status bit.

Table 1-1 Global Interrupt - Register Setting
DEVICE FAMILY TICS PRO FIELD NAME GLOBAL INTERRUPT ENABLE
REGISTER SETTING
LMK05318B, LMK05318 INT_EN R21[0] = 1
LMK5B, LMK5CA, LMK5C INT_EN R49[1] = 1

The TICS Pro software provides a visual representation of the status registers in the Status page of the LMK device profile. The Status page of the LMK5B33216 profile is shown in Figure 1-1 and the LMK05318B profile in Figure 1-2. The primary status registers, which are useful for debug and discussed in the later sections, are highlighted in red.
