PIN DESCRIPTION
36 8xC51 general purpose I/O port (USB_SUSPEND in TDA8030)
37 8xC51 general purpose I/O port (USB_WAKEUP_N in TDA8031)
38 external data memory write strobe
39 external data memory read strobe
40 12 MHz crystal output; leave open-circuit if an external clock is used
41 external 12 MHz crystal connection or input for an external clock signal
42 3.3 V regulated digital supply voltage output (decouple with 1 µF ceramic capacitor)
43 Digital ground
44 8xC51 general purpose I/O port/address 8 (available for the application)
45 8xC51 general purpose I/O port/address 9 (available for the application)
46 8xC51 general purpose I/O port/address 10 (available for the application)
47 8xC51 general purpose I/O port/address 11 (available for the application)
48 8xC51 general purpose I/O port/address 12 (available for the application)
49 8xC51 general purpose I/O port/address 13 (USB_MP_C)
50 8xC51 general purpose I/O port/address 14 (USB_MP_SEL)
51 8xC51 general purpose I/O port/address 15 (ISO_UART_CS)
52 Program Store Enable: read strobe to external program memory when executing code from
the external program memory; PSEN is activated twice each machine cycle except when two
PSEN activations are skipped during each access to external data memory. PSEN is not
activated during fetches from internal program memory.
53 Address Latch Enable/Program Pulse: output pulse for latching the low byte of the address
during an access to external memory. In normal operation ALE is emitted at a constant rate of
1/6 the oscillator frequency and can be used for external timing or clocking. It should be noted
that one ALE pulse is skipped during each access to external data memory. This pin is also
the program pulse input (PROG) during EPROM programming. ALE can be disabled by
setting SFR Auxiliary0. With this bit set ALE will be active only during a MOVX instruction.
54 External Access Enable/Programming Supply Voltage: EA must be externally held LOW to
enable the device to fetch code from external program memory locations starting with 0000H.
If EA is held HIGH the device executes from internal program memory unless the program
counter contains an address greater than 3FFFH (16 kbytes boundary). This pin also receives
the 12.75 V programming supply voltage (VPP) during EPROM programming. If security bit 1
is programmed EA will be internally latched on reset.

8.1.3.4 Time-out configuration register
The Time-Out Configuration register (TOCR) is used for setting different configurations of the time-out counter according
to Table 8; all other configurations are undefined.
The timers can operate in 3 modes:
1. Software triggered
2. Start bit triggered
3. Autoreload.
