Philips Semiconductors
The software programmable output (SWPORT1) can be
programmed to operate as a tuning indicator output.
As long as the IC has not completed a tuning action,
pin SWPORT1 remains LOW. The pin becomes HIGH,
when a preset or search tuning is completed or when a
band limit is reached.
The reference frequency divider of the synthesizer PLL is
changed when the MSB in byte 5 is set to logic 1. The
tuning system can then be clocked via pin XTAL2 at
6.5 MHz.
