8.0 OPERATION MODES
The device can operate in two different modes. The Opera-
tion mode includes the User mode and the Learning mode.
The pin definitions vary between different operation modes
as described in Table 8-1.
8.1 User Mode
In the user mode, the embedded MCU fetches program
codes from the user memory space. Please refer to the
SST65P542R Programming User’s Manual
for instruction
sets and the internal MCU programming information.
8.2 Learning Mode
To enter the learning mode, input the IR signal to the IRQ#
pin, then use the BIL and BIH instruction set to record the
input signal width. For detail information on learning mode,
please refer to the application note “Remote Controller
Learning Algorithm using SST65P542R.”
