DIR_SEL = | Selects daisy chain communication
direction. 0 = With two devices connected in daisy chain, command frame travels from COMH of the lower device to COML of the next device. 1 = With two devices connected in daisy chain, command frame travels from COML of the lower device to COMH of the next device. |
|||||||
SEND_SHUTDOWN = | Sends SHUTDOWN tone to next device
up the stack. The device receiving this bit set is unaffected. Bit
is self-cleared. 0 = Ready 1 = Send SHUTDOWN tone up the stack |
|||||||
SEND_WAKE = | Sends WAKE tone to next device up
the stack. Bit is self-cleared. 0 = Ready 1 = Send WAKE tone to next device up the stack. |
|||||||
SEND_SLPTOACT = | Sends SLEEPtoACTIVE tone up the
stack. Bit is self-cleared. 0 = Ready 1 = Send SLEEPtoACTIVE tone up the stack |
|||||||
GOTO_SHUTDOWN = | Transitions device to SHUTDOWN mode.
Bit is self-cleared. 0 = Ready 1 = Enter SHUTDOWN mode |
|||||||
GOTO_SLEEP = | Transitions device to SLEEP mode.
Bit is self-cleared. 0 = Ready 1 = Enter SLEEP mode |
|||||||
SOFT_RESET = | Resets the digital to OTP default.
Bit is self-cleared. Setting this bit will cause the device to
generate WAKE tone to the upper stack devices. 0 = Ready 1 = Reset device |
|||||||
ADDR_WR = | Enables device to start
auto-addressing. When this bit is set, device will not forward the
first transition it receives, allowing the device address to be
written to a single device. See Section 9.3.6.1.3.2 for details. 0 = Not performing auto-address. Device forwards communication transaction as normal. 1 = Device is being auto-addressed; the first communication transaction it receives will not be forwarded. |
Host should not write multiple bits at the same to CONTROL1 register. The following shows the priority behavior if multiple bits are written at the same write command to CONTROL1
