KL1512 - Process data exchange

Control byte in process data exchange (REG=0)

During process data exchange, the control byte is used to trigger various actions in the KL1512 counter
terminal:

Bit

Name

REG=0

CNT_SET

CNT_INH

CNT_OVL

CNT_CLR

CNT_DEC

Bit

Function

REG=0

0 for Process data mode

Not used

CNT_SET

The counter is set to the value that is specified via the process data.
Setting of the counter is edge-controlled.

CNT_INH

The counter is stopped, as long as this bit is active. The present counter value is saved.

Not used

CNT_OVL

If this bit is set, the counter is stopped,

if it reaches 0xFFFF while counting forwards

if it reaches 0x0000 while counting backwards

CNT_CLR

The counter is set to the value 0x0000. Setting of the counter is edge controlled.

CNT_DEC

If this bit is set, the counter is decremented with every positive edge.

Status byte in process data exchange (REG=0)

The status byte is transferred from the terminal to the controller. The status byte contains various status bits
of the KL1512 counter terminal

Bit

Name

REG=0

SET_ACK

INH_ACK

OVL_ACK

CLR_ACK

DEC_ACK

Bit

Function

REG=0

0 for Process data mode

Not used

SET_ACK

Acknowledgement for CNT_SET: The data for setting the counter was taken over by the terminal.

INH_ACK

Acknowledgement for CNT_INH: The counter is stopped.

Not used

OVL_ACK

Acknowledgement for CNT_OVL: If this bit is set, the counter is stopped,

if it reaches 0xFFFF while counting forwards

if it reaches 0x0000 while counting backwards

CLR_ACK

Acknowledgement for CNT_CLR: The counter is set to the value 0x0000. Setting of the counter is edge controlled.

DEC_ACK

Acknowledgement for CNT_DEC: If this bit is set, the counter is decremented with every positive edge.
