This register is used to control the counter/timers. A counter is selected with bit 7, and then a 1 is written to any ONE of bits 6 – 0 to select the desired operation for that counter. The other bits and associated functions are not affected. Thus only one operation can be performed at a time.

CTRNO

Counter no., 0 or 1

LATCH

Latch the selected counter so that its value may be read. The counter must be

 

latched before it is read. Reading from registers 12-14 returns the most recently

 

latched value. If you are reading Counter 1 data, read only Base + 12 and Base + 13.

 

Any data in Base + 14 will be from the previous Counter 0 access.

GTDIS

Disable external gating for the selected counter.

GTEN

Enable external gating for the selected counter. If enabled, the associated gate

 

signal GATE0 or GATE1 controls counting on the counter. If the GATEn signal is

 

high, counting is enabled. If the GATEn signal is low, counting is disabled.

CTDIS

Disable counting on the selected counter. The counter will ignore input pulses.

CTEN

Enable counting on the selected counter. The counter will decrement on each input

 

pulse.

LOAD

Load the selected counter with the data written to Base + 12 through Base + 14 or

 

Base + 12 and Base + 13 (depending on which counter is being loaded).

CLR

Clear the current counter (set its value to 0).

To load a counter: First write the load value to Base + 12 and Base + 13 (for Counter 1) or Base

+12 through Base + 14 (for Counter 0). Then write a Load command to Base + 15. For example, to load Counter 0 with the hex value 123456:

♦Write 0x12 to Base + 14 (these three bytes can be written to in any order)

♦Write 0x34 to Base + 13

♦Write 0x56 to Base + 12

♦Write 0x02 to Base + 15 to load counter 0

To enable counting: Write 0x04 (ctr 0) or 0x84 (ctr 1) to Base + 15.

To stop counting: Write 0x08 (ctr 0) or 0x88 (ctr 1) to Base + 15.

To read a counter: First latch it, then read the value:

♦Write 0x40 to Base + 15 to latch counter 0 or 0xC0 to latch counter 1

♦Read LSB from Base +12

♦Read Middle Byte from Base + 13

♦Read MSB from Base + 14

♦Assemble 3 bytes into the current counter value

More complete counter programming operations are provided in chapter 20 on page 59.
