Bit 7 =
TMZ
: Timer Zero bit
A low-to-high transition indicates that the timer
count register has decrement to zero. This
must be cleared by user software before starting a
new count.
Bit 6 =
ETI
: Enable Timer Interrup
When set, enables the timer interrupt request. If
ETI=0 the timer interrupt is disabled. If ETI=1 and
TMZ=1 an interrupt request is generated.
Bit 5 =
D5
: Reserved
Must be set to “1”.
Bit 4 =
D4
Do not care.
Bit 3 =
PSI
: Prescaler Initialize Bit
Used to initialize the prescaler and inhibit its
counting. When PSI=“0” the prescaler is set to
7Fh and the counter is inhibited. When PSI=“1”
the prescaler is enabled to count downwards. As
long as PSI=“0” both counter and prescaler are
not running.
Bit 2, 1, 0 =
PS2, PS1, PS0
: Prescaler Mux. Se-
lect.These bits select the division ratio of the pres-
caler register.
