Bit Name
Default
Bit No.
This register is valid when the PULS[3:0] bits (b3~0, T1/J1-023H) are set to ‘11xx’.
= 0: Disable the read/write operation to the pulse template RAM.
= 1: Enable the read/write operation to the pulse template RAM.
= 0: Write the data to the pulse template RAM.
= 1: Read the data to the pulse template RAM.
These bits specify one Unit Interval (UI) address.
= 00: UI addressed 0 is specified.
= 01: UI addressed 1 is specified.
= 10: UI addressed 2 is specified.
= 11: UI addressed 3 is specified.
There bits specify one sample address. There are 16 samples in each UI.
