2. Asynchronous serial interface reception error status register 61 (ASIS61), asynchronous
the high level when POWER61 = 0 during transmission.
serial interface transmission status register 61 (ASIF61), bit 7 (SBRF61) and bit 6 (SBRT61)
of asynchronous serial interface control register 61 (ASICL61), and receive buffer register 61
(RXB61) are reset.
Disables operation of the internal operation clock (fixes the clock to low level) and asynchronously
resets the internal circuit
Enables operation of the internal operation clock
Disables transmission (synchronously resets the transmission circuit).
Enables transmission
Disables reception (synchronously resets the reception circuit).
