AUTO-RELOAD TIMER (Cont’d)

Bist 7-5 = PS2-PS0: Prescaler Division Selection
Bits 2-0. These bits determine the Prescaler divi-
sion ratio. The prescaler itself is not affected by
these bits. The prescaler division ratio is listed in the
following table:
Table 14. Prescaler Division Ratio Selection
Bit 4 = D4: Reserved. Must be kept reset.
Bit 3-2 = SL1-SL0: Timer Input Edge Control Bits 1-
0. These bits control the edge function of the Timer
input pin for external synchronization. If bit SL0 is re-
set, edge detection is disabled; if set edge detection
is enabled. If bit SL1 is reset, the AR Timer input pin
is rising edge sensitive; if set, it is falling edge sen-
sitive.
Bit 1-0 = CC1-CC0: Clock Source Select Bit 1-0.
These bits select the clock source for the AR Timer
through the AR Multiplexer. The programming of
the clock sources is explained in the following Table
15 :
Table 15. Clock Source Selection.
AR Load Register ARLR. The ARLR load register
is used to read or write the ARTC counter register
“on the fly” (while it is counting). The ARLR regis-
ter is not affected by system reset.
AR Load Register (ARLR)
Address: DBh

Bit 7-0 = D7-D0: Load Register Data Bits. These
are the load register data bits.
AR Reload/Capture Register. The ARRC re-
load/capture register is used to hold the auto-re-
load value which is automatically loaded into the
counter when overflow occurs.
AR Reload/Capture (ARRC)
Address: D9h

Read/Write
Bit 7-0 = D7-D0: Reload/Capture Data Bits. These
are the Reload/Capture register data bits.
AR Compare Register. The CP compare register
is used to hold the compare value for the compare
function.
AR Compare Register (ARCP)
Address: DAh
—
Read/Write
Bit 7-0 = D7-D0: Compare Data Bits. These are
the Compare register data bits.
