PRODUCTION DATA
The Remote Channel Open Status register reports the state of the connection of remote channels one through eight. Table 7-7 lists the status register bits. The Remote Channel Open Status register is read-only and is read by accessing pointer address 23h.
REMOTE CHANNEL OPEN STATUS REGISTER (READ = 23h, WRITE = N/A) | ||
---|---|---|
BIT NUMBER | BIT NAME | FUNCTION |
15 | R8OPEN | 1 when Remote 8 channel is an open circuit |
14 | R7OPEN | 1 when Remote 7 channel is an open circuit |
13 | R6OPEN | 1 when Remote 6 channel is an open circuit |
12 | R5OPEN | 1 when Remote 5 channel is an open circuit |
11 | R4OPEN | 1 when Remote 4 channel is an open circuit |
10 | R3OPEN | 1 when Remote 3 channel is an open circuit |
9 | R2OPEN | 1 when Remote 2 channel is an open circuit |
8 | R1OPEN | 1 when Remote 1 channel is an open circuit |
7:0 | 0 | Reserved for future use; always reports 0. |
The R8OPEN:R1OPEN bits indicate an open-circuit condition on remote sensors eight through one, respectively. The setting of these flags does not directly affect the state of the THERM or THERM2 output pins. Indirectly, the temperature reading(s) may be erroneous and exceed the respective THERM and THERM2 limits, activating the THERM or THERM2 output pins.
