I/O Port Drive Capability
The maximum allowable continuous current that the
device can sink on an I/O port is defined in the
following table.
Maximum sink current on one given I/O
Maximum total sink current for P0
Maximum total sink current for P1, 2, 3,4
Maximum total sink current on all I/O
It is not recommended to exceed the sink current
outlined in the above table. Doing so will likely result in
the low-level output voltage exceeding device
specifications and in turn affect device reliability.
The VMX51C900 I/O ports are not designed to source
current.
Timers
10mA
26mA
15mA
71mA
The VMX51C900 includes three 16-bit timers: Timer0,
Timer1 and Timer2.
The timers can operate in two modes:
Event counting mode
Timer mode
When operating in event counting mode, the counter is
incremented each time an external event, such as a
transition in the logical state of the timer input (T0, T1,
T2 input), is detected. When operating in timer mode,
the counter is incremented by the microcontroller’s
system clock (Fosc/12) or by a divided version of it.
Timer0 and Timer1
Timers0 and 1 have four modes of operation. These
modes allow the user to change the size of the
counting register or to authorize an automatic reload
when encountering a specific value. Timer1 can also
be used as a baud rate generator to generate
communication frequencies for the serial interface.
Timer0 and Timer1 are configured by the TMOD and
TCON registers.
