TIMER

(Cont’d)
4.2.5 TIMER 2 Registers
Timer Status Control Register (TSCR)
Address: 0D7h
—
Read/Write
Bit 7 =
TMZ
:
Timer Zero bit
A low-to-high transition indicates that the timer
count register has decrement to zero. This bit
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 count-
ing. When PSI=“0” the prescaler is set to 7Fh and
the counter is inhibited. When PSI=“1” the prescal-
er is enabled to count downwards. As long as
PSI=“0” both counter and prescaler are not run-
ning.
Bit 2, 1, 0 =
PS2, PS1, PS0
:
Prescaler Mux. Se-
lect.
These bits select the division ratio of the pres-
caler register.
Timer Counter Register (TCR)

Counter Bits.
Prescaler Register PSC

Bit 7 =
D7
: Always read as "0".
Bit 6-0 =
