These bits are not implemented on PIC18F2331/2431 devices and read as ‘0’.
For Timer5 to operate during Sleep mode, T5SYNC must be set.

purpose timer or a Special Event Trigger delay timer.
When used as a general purpose timer, it can be
configured to generate a delayed Special Event Trigger
(e.g., an ADC Special Event Trigger) using a
preprogrammed period delay.
Timer5 is controlled through the Timer5 Control register
(T5CON), shown in
enabled or disabled by setting or clearing the control bit
TMR5ON (T5CON<0>).
