Enhanced Secure Digital Host Controller
There are three scenarios when AUTOC12ERR can be changed:
The timing of generating the Auto CMD12 error and writing to the command register is asynchronous. The
command may be blocked by any Auto CMD12 error causing CNIBAC12E to be set. Therefore, it is
suggested to read this register only when IRQSTAT[AC12E] is set. An Auto CMD12 error interrupt is
generated when one of the error bits 0–4 is set1. The CNIBAC12E error bit does not generate an interrupt.
20-32
1. When eSDHC is going to issue Auto CMD12
2. At the end bit of an Auto CMD12 response
3. Before reading AUTOC12ERR[CNIBAC12E]
— Set AC12NE if Auto CMD12 cannot be issued due to an error in the previous command.
— Clear AC12NE if Auto CMD12 is issued.
— Check received responses by checking the error bits 1–4.
— Set if error is detected.
— Clear if error is not detected.
— Set CNIBAC12E if there is a command that cannot be issued
— Clear CNIBAC12E if there is no command to issue
