DDC STATUS REGISTER 2 (DDCSR2)
Read Only
Reset Value: 0000 0000 (00h)
Bits [7:5] = Reserved.
Forced to 0 by hardware.
Bit 4 = AF
Acknowledge failure
.
This bit is set by hardware when no acknowledge is returned. An interrupt is generated if ITE = 1. It
is cleared by software by reading the SR2 register or by hardware when the interface is disabled
(PE = 0).
The SCL line is not held low when AF = 1.
0
No acknowledge failure
1
Acknowledge failure
Bit 3 = STOPF
Stop detection.
This bit is set by hardware when a Stop condition is detected on the bus after an acknowledge (if
ACK = 1). An interrupt is generated if ITE = 1. It is cleared by software by reading the SR2 register
or by hardware when the interface is disabled (PE = 0). The SCL line is not held low when STOPF
= 1.
0
No Stop condition detected
1
Stop condition detected
Bit 2 = Reserved.
Forced to 0 by hardware.
Bit 1 = BERR
Bus error.
This bit is set by hardware when the interface detects a misplaced Start or Stop condition. An
interrupt is generated if ITE = 1. It is cleared by software by reading the SR2 register or by hardware
when the interface is disabled (PE = 0).
The SCL line is not held low when BERR = 1.
0
No misplaced Start or Stop condition
1
Misplaced Start or Stop condition
Bit 0 = DDCIF
DDC/CI address detected.
This bit is set by hardware when the DDC/CI address (6Eh/6Fh) is detected on the bus when
DDCIEN = 1. It is cleared by hardware when a Stop condition (STOPF = 1) is detected, or when the
interface is disabled (PE = 0).
0
No DDC/CI address detected on bus
1
DDC/CI address detected on bus
