Microcontrollers for PAL/SECAM TV
with OSD and VST
P8xCx66 family
10.5
Data Shift Register (S1DAT)
S1DAT contains the serial data to be transmitted or data that has just been received. Bit 7 is transmitted or received first.
Table 13
Data Shift Register (SFR address DAH)
10.6
Slave Address Register (S1ADR)
This 8-bit register may be loaded with the 7-bit slave address to which the controller will respond when programmed as
slave receiver/transmitter. The LSB bit (GC) is used to determine whether the general CALL address is recognized.

Description of S1ADR bits
10.7
Internal Status Register (S1IST)
S1IST is an 8-bit read-only Special Function Register and will exist in the design but is not mapped for the user.

C-bus enable.
This bit selects the functions of pins 39 and 40 for the SDIP42 package
(or pins 64 and 65 for the PLCC68 package). When I

CE = 1, the alternative functions
SCL and SDA are selected. When I

CE = 0, these pins act as port lines P1.5 and P1.6.
These bits are not used.
