Start Checksum Calculation (CKSTART)

This single instruction is used to start the checksum calculation of the enetered data used to configure the device.

COMMAND LIST

(*) For this two commands the bit set in the COMEN register are not considered.

COMMAND DESCRIPTION

Each command is transferred on every channel that has the proper bit in the COMEN register set to 1.

Block Enable command (BLKEN)

Reset Value=00h

The command is used to enable/disable the B, Z, R and X blocks

BE=1: The B block is equal to an open circuit

BE=0: The B block is configured as defined in the Ringing state or with the programmed value

ZE=1: The Z block is equal to an open circuit

ZE=0: The Z block is configured as defined in the Ringing state or with the programmed value

RE=1: The R block is equal to a short circuit

RE=0: The R block is configured as defined in the Ringing state or with the programmed value

XE=1: The X block is equal to a short circuit

XE=0: The X block is configured as defined in the Ringing state or with the programmed value
