Description

EXSP
Extended SP Enable.
When set to 1 by the user, the stack rolls over from SPH/SP = 00FFH to 0100H.
When set to 0 by the user, the stack rolls over from SP = FFH to SP = 00H.
6
PWPO
PWM Pin Out Selection.
Set to 1 by the user to select P3.4 and P3.3 as the PWM output pins.
Set to 0 by the user to select P2.6 and P2.7 as the PWM output pins.
5
DBUF
DAC Output Buffer.
Set to 1 by the user to bypass the DAC output buffer.
Set to 0 by the user to enable the DAC output buffer.
4
EPM2
Flash/EE Controller and PWM Clock Frequency Configuration Bits.
Frequency should be configured such that FOSC/Divide Factor = 32 kHz + 50%.

MSPI
Set to 1 by the user to move the SPI functionality of MISO, MOSI, and SCLOCK to P3.3, P3.4, and P3.5,
respectively.
Set to 0 by the user to leave the SPI functionality as usual on MISO, MOSI, and SCLOCK pins.
0
XRAMEN
XRAM Enable Bit.
When set to 1 by the user, the internal XRAM is mapped into the lower two kBytes of the external address
space.
When set to 0 by the user, the internal XRAM is not accessible, and the external data memory is mapped into
the lower two kBytes of external data memory.
1 Note that the Flash/EE controller bits EPM2, EPM1, EPM0 are set to their correct values depending on the crystal frequency at power-up. The user should not modify
these bits so all instructions to the CFG841 register should use the ORL, XRL, or ANL instructions. Value of 10H is for 11.0592 MHz crystal.
