LdICR
EEPW
Load internal calibration register at address given in ICRA with data from DHR[15:0].
EEPROM write of 8 data bits from DHR[7:0] to address location pointed by IEEA [9:0].

ERASE
RdICR
RdEEP
Erase all of EEPROM (all bytes equal FFhex).
Read internal calibration register as pointed to by ICRA and load data into DHR[15:0].
Read internal EEPROM location and load data into DHR[7:0] pointed by IEEA [9:0].

PageErase
Read interface register set pointer IRSP[3:0]. See Table 13.
Output the multiplexed analog signal onto OUT. The analog location is specified in ALOC[3:0]
(Table 15) and the duration (in byte times) that the signal is asserted onto the pin is specified in
ATIM[3:0] (Table 14).
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.
