Philips Semiconductors TEA5880TS

Integrated FM stereo radio IC for host processor tuning

[1] The frequency is decreased when increasing the content of this register.

[1] The frequency is increased when increasing the content of this register.

[1] This register does not have an address. To read the status register, latch its content into the PISO (using

L_STS bit in control register B) then read out the PISO.

[1] This register does not have an address. To read the counter register, latch its content into the PISO (using

L_CNT bit in control register B) then read out the PISO.
