NAME
DESCRIPTION
0000
LdICR
Load internal calibration register at address given in ICRA with data from DHR[15:0].
0001
EEPW
EEPROM write of 8 data bits from DHR[7:0] to address location pointed by IEEA [9:0].
0010
ERASE
Erase all of EEPROM (all bytes equal FFhex).
0011
RdICR
Read internal calibration register as pointed to by ICRA and load data into DHR[15:0].
0100
RdEEP
Read internal EEPROM location and load data into DHR[7:0] pointed by IEEA [9:0].

0111
1000 to
1111
RdIRS
RdAlg
PageErase
Read interface register set pointer IRSP[3:0]. See Table 12.
Output the multiplexed analog signal onto OUT. The analog location is specified in ALOC[3:0]
(Table 14) and the duration (in byte times) that the signal is asserted onto the pin is specified in
ATIM[3:0] (Table 13).
Erases the page of the EEPROM as pointed by IEEA[9:6]. There are 64 bytes per page and thus 12
pages in the EEPROM.
Reserved Reserved.
