T3CNT (0xCA) – Timer 3 Counter

Bit Name

Reset R/W Description

7:0 CNT[7:0]

0x00 R

Timer count byte. Contains the current value of the 8-bit counter

T3CTL (0xCB) – Timer 3 Control

Bit Name

Reset R/W Description

7:5 DIV[2:0]

000

R/W Prescaler divider value. Generates the active clock edge used to update the

counter as follows:

000 Tick frequency /1

001 Tick frequency /2

010 Tick frequency /4

011 Tick frequency /8

100 Tick frequency /16

101 Tick frequency /32

110 Tick frequency /64

111 Tick frequency /128

Note: Changes to these bits has immediate effect on the frequency of the active

clock edges.

R/W Timer 3 mode select. The timer operating mode is selected as follows:

00 Free running, repeatedly count from 0x00 to 0xFF

01 Down, count from T3CC0 to 0x00

10 Modulo, repeatedly count from 0x00 to T3CC0

11 Up/down, repeatedly count from 0x00 to T3CC0 and from T3CC0 down

to 0x00
