Table 11. CRIL Command Codes
CRIL[3:0] 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].
0101 RdIRS Read interface register set pointer IRSP[3:0]. See Table 13.
0110 RdAlg
Output the multiplexed analog signal onto OUT. The analog location is specied in ALOC[3:0] (Table
15) and the duration (in byte times) that the signal is asserted onto the pin is specied in ATIM[3:0]
(Table 14).
0111 PageErase
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.
