Note 1: In this diagram, the use of “x’ in registers TxCON, TMRx, PRx, TxCK refers to either
Timer2 or Timer4; the use of ‘y’ in registers TyCON, TMRy, PRy, TyIF refers to either Timer3 or Timer5.
2: TxCK pins not available on 64-pin devices.
3: ADC event trigger is available only on Timer2/3 pair.
