19.2.10 Port Function Control Register (PFCR)

Port Function Control Register
b7 b6 b5 b4 b3 b2 b1
This register is enabled only when the INV03 bit in the INVC0 register is set to 1 (three-phase motor
control timer output enabled). Set the TPRC0 bit in the TPRC register to 1 (write enabled) before
rewriting this register.

19.2.11 Three-Phase Protect Control Register (TPRC)

Three-Phase Protect Control Register
b7 b6 b5 b4 b3 b2 b1
Once the TPRC0 bit is set to 1 (write enabled) by a program, the set value 1 is retained. To change the
register protected by this bit, follow these steps:
(1) Set the TPRC0 bit to 1.
(2) Set a value to the PFCR register.
(3) Set the TPRC0 bit to 0 (write disabled).
