I/O Memory Of Serial Interface - Epson S1C33210 Technical Manual

III PERIPHERAL BLOCK: SERIAL INTERFACE

I/O Memory of Serial Interface

Table 8.14 shows the control bits of the serial interface.
For details on the I/O memory of the prescaler that is used to set clocks, as well of that of 8-bit programmable timers,
refer to "Prescaler" and "8-Bit Programmable Timers", respectively.
