5.3. Telegram Codes
Sync Bit
Each telegram starts with the Sync Bit. This logical
“
0
”
pulse defines the exact timing for t
p0
.
Command Bits (COM)
The Command code contains 3 bits and is a binary
number. Table 5
–
2 shows the available commands
and the corresponding codes for the HAL 805.
Command Parity Bit (CP)
This parity bit is
“
1
”
if the number of zeros within the 3
Command Bits is uneven. The parity bit is
“
0
”
, if the
number of zeros is even.
Address Bits (ADR)
The Address code contains 4 bits and is a binary num-
ber. Table 5
–
3 shows the available addresses for the
HAL 805 registers.
Address Parity Bit (AP)
This parity bit is
“
1
”
if the number of zeros within the 4
Address bits is uneven. The parity bit is
“
0
”
if the num-
ber of zeros is even.
Data Bits (DAT)
The 14 Data Bits contain the register information.
The registers use different number formats for the
Data Bits. These formats are explained in Section 5.4.
In the Write command, the last bits are valid. If, for
example, the TC register (6 bits) is written, only the
last 6 bits are valid.
In the Read command, the first bits are valid. If, for
example, the TC register (6 bits) is read, only the first 6
bits are valid.
Data Parity Bit (DP)
This parity bit is
“
1
”
if the number of zeros within the
binary number is even. The parity bit is
“
0
”
if the num-
ber of zeros is uneven.
Acknowledge
After each telegram, the output answers with the
Acknowledge signal. This logical
“
0
”
pulse defines the
exact timing for t
pOUT
.
