I have 3 queries below:
1. I need a datasheet of the 8052 core in TUSB3210 - containing
the details about the SFR’s, timer registers (TUSB3210 datasheet says it has tow
16-bit timers need to know the addresses), Port registers (P0-P4: need to know whether to configure
them either as input/output) and flag register associated with port2 which can
generate interrupt, interrupt configuration, Memory layout along with
instruction manual and debugging interfaces.
Basically need to have a complete data sheet of the 8052 core that is used in
the TUSB3210.
2. Can the outputs of
TUSB3210 gpio ports (P0, P1, P2 and P3) drive 4mA current when driving a
logic high level?
The datasheet seems to suggest that outputs are open drain
type, and can only sink current but not source.
3. There is mention of active pullups (100 uA) on P0, P1, P2 and P3. Are these
pullups configurable?
Also, are the pullups applicable when the ports are
configured as outputs?
Please let me know ASAP. Thanks.
