Synthesizer programming data
Data for programming a PLL synthesizer via pins ZSD,
ZSC and ZLE can be stored in row 1 of the EEPROM.
Six bytes are available starting from address 08H.
Data is transferred in two serial blocks of 24 bits each,
starting with bit 0 (MSB) of block 1. Any unused bits must
be programmed at the beginning of a block.
7.56
Identifier storage allocation
Up to 6 different identifiers can be stored in EEPROM for
matching with incoming data. The PCD5003 can
distinguish two types of identifiers:
User addresses (RIC)
User Programmable Sync Words (UPSW).
Identifiers are stored in EEPROM rows 2, 3 and 4. Each
identifier location consists of 3 bytes in the same column.
The identifier number is equal to the column number + 1.
Only the last 4 identifiers (numbers 3 to 6) can be
programmed as a UPSW. Identifiers 1 and 2 always
represent RICs. A UPSW represents an unused address
and must differ by more than 6 bits from preamble to
guarantee detection.
The standard POCSAG sync word is always enabled and
has identifier number 7.
Table 26 shows the memory locations of the 6 identifiers.
The bit allocation per identifier is given in Table 27.
