Signal Description
3.4.5 Timer 1 and Timer 2 Pin Functions
3.4.6 Queued Analog-to-Digital Converter (QADC) Pin Functions
Advance Information
112
NOTE:
The timer modules can support up to four external pins each.
Only the pins associated with each timer are controlled by the register
bits for the corresponding timer.
Full timer port pin functions are supported.
The default reset value for PUPT is 0. Thus, the pullup function is
disabled by default.
The sync input is tied off and this function is not supported.
This implementation is a limited pin out version of the original QADC.
Limiting the number of pins lowers the over all pin count of the complete
package. The lower pin count is achieved by utilizing 8 of 16 pins of the
original full pin set. The available pins are, PQA4–PQA3, PQA1–PQA0,
and PQB3–PQB0. All of the original functionality of the module is
implemented with exception of limiting the total number of multiplexed
channels. By using four external multiplexer chips, the maximum
number of channels is 18. In nonmultiplexed mode, the maximum
number of channels is eight.
