Register Set
TABLE 2. OPERATION MODE
There are eight registers available in the ISL29033. Table 1
summarizes their functions.
Command Register I 00 (Hex)
The first command register has the following functions:
1. Operation Mode: Bits 7, 6, and 5. These three bits determine
the operation mode of the device (Table 2). Interrupt flag:
Bit 2. This is the status bit of the interrupt (Table 3). The bit is
set to logic high when the interrupt thresholds have been
triggered (out of threshold window), and to logic low when not
yet triggered. When activated and the interrupt is triggered,
the INT pin goes low, and the interrupt status bit goes high
until the status bit is polled through the I 2 C read command.
Both the INT output and the interrupt status bit are
automatically cleared at the end of the 8-bit (00h) command
register transfer.
