Page number : - MAG = magazine, PU = page units, PT = page tens.
Page sub-code : - MU = minutes units, MT = minutes tens, HU = hours units, HT = hours tens.
PBLF = page being looked for, FOUND = low for page found, HAM = hamming error in byte, C4-14 = control bits.
) VPS DATA (see Table 10)
t(s VPS data are stored in row 25 chapter 5 as shown
c in Table 10 when VPS enable bit (D4 of R8 regis-
u ter) is set. VPS data bits are decoded and stored
d in a received area with biphase error bit.
ro 8/30/2 data are stored as received (without ham-
P ming decoding) in Row 23 chapter 5 according to
Table 10.
te 8/30 packet and VPS data decoding is the respon-
le sibility of the control software. The decoder simply
o stores transmitted data.
s I2C Bus Register Map (see Table 11)
b Registers R0 to R10 are write only whilst R11A is
O a read/write and R11B is read only.
The automatic succession on a byte by byte basis
is indicated by the arrows in Table 10.
In the normal operating mode TB should be set to
logic level 0.
After power-up the contents of the registers are as
follows: all bits in registers R0 to R11A are cleared
to zero with the exception of bits D0 and D1 in reg-
isters R5 and R6 which are set to logical one.
After power-up all the memory bytes are preset to
hexadecimal value 20H (space) with the exception
of the byte corresponding to row 0 of column 7 of
chapter 0 which is set to the value corresponding
to "alpha white" hexadecimal value 07H.
