Not Bit addressable
Serial Peripheral Data Register
(SPDAT)
The Serial Peripheral Data Register (Table 76) is a read/write buffer for the receive data
register. A write to SPDAT places data directly into the shift register. No transmit buffer is
available in this model.
A Read of the SPDAT returns the value located in the receive buffer and not the content
of the shift register.
Table 76. SPDAT Register
SPDAT - Serial Peripheral Data Register (0C5H)
Reset Value = Indeterminate
R7:R0: Receive data bits
SPCON, SPSTA and SPDAT registers may be read and written at any time while there
is no on-going exchange. However, special care should be taken when writing to them
while a transmission is on-going:
•
Do not change SPR2, SPR1 and SPR0
•
Do not change CPHA and CPOL
•
Do not change MSTR
•
Clearing SPEN would immediately disable the peripheral
•
Writing to the SPDAT will cause an overflow
