4.6.1 Overview
Timer1(TMR1) is an eight-bit clock counter with a programmable prescaler. It is
designed for the SPI module as a baud rate clock generator. TMR1 can be read and
written and cleared on any reset conditions. If employed, it can be turned down for
power saving by setting TMR1EN bit [T1CON<2>] to 0.
