Table 32. PRT Timer Out Operation Example
Each programmable reload timer is controlled using five 8-bit registers. These registers are
the TIMER Control register, TIMER Reload Low Byte register, TIMER Reload High Byte
register, TIMER Data Low Byte register, and TIMER Data High Byte register.
The Timer Control register can be read or written to. The timer reload registers are Write
Only and are located at the same I/O address as the timer data registers, which are Read
Only.
Timer Control Register
The TIMER Control register, detailed in Timer Control Register (TMR0_CTL = 0080h,
TMR1_CTL = 0083h, TMR2_CTL = 0086h, TMR3_CTL = 0089h, TMR4_CTL =
008Ch, or TMR5_CTL = 008Fh), is used to control operation of the timer, including
