(b7-b6)
No register bits. If necessary, set to 0. Read as 0
—
This register is valid only when the INV03 bit in the INVC0 register is set to 1 (three-phase motor control
timer output enabled). Write to this register after the TPRC0 bit in the TPRC register is set to 1 (write
enabled).

No register bits. If necessary, set to 0. Read as 0
—
Once the TPRC0 bit is set to 1 (write enabled) by a program, the set value 1 is retained. To change the
registers protected by this bit, follow the steps below.
(1) Set the TPRC0 bit to 1.
(2) Set values in the PFCR register.
(3) Set the TPRC0 bit to 0 (write disabled).
