8.10 Mode control
Two pins are dedicated to control the operational modes of
the SAA8112HL: pin M for the DSP and pin UCM for the
microcontroller (see Table 4). They are independent of
each other.
8.11 SNERT (UART) interface - DSP registers
The DSP registers can be accessed via a SNERT
interface. This SNERT interface is equivalent to the UART
mode 0 interface of the 80C51 microcontroller. The DSP
register list is shown in Table 5.
