17.3.5 Carrier Frequency Output
17.3.5.1 Carrier Frequency Output Operation
A carrier frequency signal can be output from port n by setting the PnPMD Register.
The carrier frequency output can be applied to all output except analogue output.
See Table 17-2 "List of Registers/Bits" for pins supporting the carrier frequency output function.
For the carrier frequency output, either of 16-bit timer 0 output (TMH0OUT) or functional timer 0 output can be used
through setting the PnPSL register.
See Chapter 8 "16-Bit Timer" for details of 16-bit timer 0, and Chapter 9 "Functional Timer" for functional timer 0.
Figures 17-3 and 17-4 show an example of use of the carrier frequency output function.
Figure 17-3 Example of Carrier Frequency Output When P03 Pin is Assigned to UART Output Pin
(P03PEN bit of P3PMD register="1", P03PLVL bit= "0")
Figure 17-4 Example of Carrier Frequency Output When P03 Pin is Assigned to UART Output Pin
(P03PEN bit of P3PMD register="1", P03PLVL bit= "1")
17.3.5.2 Carrier Frequency Output Function Setting Procedure
Figure 17-5 shows an example of the carrier frequency output function setting procedure (with P03 pin used, SU0_TXD0
shared function, functional timer 0 output (FTM0P) used as a timer, carrier frequency output at "L" level).
