SPI Registers Control and status bits for the Serial Periph-
eral Interface are contained in registers SPCR (shown in
are contained in the SPDR register. Writing the SPI data
register during serial data transfer sets the Write Collision
bit, WCOL, in the SPSR register. The SPDR is double buff-
ered for writing and the values in SPDR are not changed by
Reset.
Interrupt Registers The global interrupt enable bit and the
individual interrupt enable bits are in the IE register. In
addition, the individual interrupt enable bit for the SPI is in
the SPCR register. Two priorities can be set for each of the
six interrupt sources in the IP register.
Dual Data Pointer Registers To facilitate accessing exter-
nal data memory, two banks of 16-bit Data Pointer
Registers are provided: DP0 at SFR address locations
82H-83H and DP1 at 84H-85H. Bit DPS = 0 in SFR WCON
selects DP0 and DPS = 1 selects DP1. The user should
always initalize the DPS bit to the appropriate value before
accessing the respective Data Pointer register.
Power Off Flag The Power Off Flag (POF) is located at
bit_4 (PCON.4) in the PCON SFR. POF is set to “1” during
power up. It can be set and reset under software control
and is not affected by RESET.

PS0
Prescaler Bits for the Watchdog Timer. When all three bits are set to “0”, the watchdog timer has a nominal period of 16
ms. When all three bits are set to “1”, the nominal period is 2048 ms.
DPS
Data Pointer Register Select. DPS = 0 selects the first bank of Data Pointer Register, DP0, and DPS = 1 selects the
second bank, DP1
WDTRST
Watchdog Timer Reset. Each time this bit is set to “1” by user software, a pulse is generated to reset the watchdog
timer. The WDTRST bit is then automatically reset to “0” in the next instruction cycle. The WDTRST bit is Write-Only.
WDTEN
Watchdog Timer Enable Bit. WDTEN = 1 enables the watchdog timer and WDTEN = 0 disables the watchdog timer.
