In addition to the timers described in this chapter, the Baud Rate Generators for any
unused UART, SPI, or I
functionality. See the respective serial communication peripheral chapters for
information on using the Baud Rate Generators as timers.

The timers are 16-bit up-counters. Minimum time-out delay is set by loading the value
0001H
to 1. Maximum time-out delay is set by loading the value
High and Low Byte registers and setting the prescale value to 128. If the Timer reaches
