Bits [7:4] — See 4.3 System Initialization Registers, page 22.
Bits 3, 1, 0 — Not implemented. Reads always return zero and writes have no effect.
SPRBYP — SPI Baud Rate Counter Bypass
52
OPT2 — System Configuration Option Register 2
RESET
When the SPI baud rate counter is bypassed, the SPI can transmit at a maximum master mode baud
rate equal to the E-clock frequency. SPRBYP is present only on the MC68HC11FC0 and overrides
the setting of SPR[1:0] in SPCR.
0 = Enable SPI baud rate counter
1 = Bypass SPI baud rate counter
