Table 62. SWNEB Bit Function

C Mode Disable)
DDCCON.bit2 = 1 (DDC1 Mode Enable) or
S1CON.bit6 = 1 (I

C Mode Enable)
0
In this state, the DDC unit is disabled. The DDC
SRAM cannot be accessed by the MCU. No MCU
interrupt and no DDC activity will occur.
MCU cannot access internal DDC SRAM: DDC
SRAM address space is re-assigned to external
data space.
In this state, the DDC is enabled and the unit is in
automatic mode. The DDC SRAM cannot be
accessed by the MCU – only the DDC unit has
access.
MCU cannot access internal DDC SRAM: data
space FF00h-FFFFh is dedicated to DDC SRAM.
1
In this state, the DDC unit is disabled, BUT with
SWENB=1, the MCU can access the SRAM. This
state is used to load the DDC SRAM with the
correct data for automatic modes. No MCU
interrupt and no DDC activity will occur.
MCU can access DDC SRAM: data space FF00h-
FFFFh is dedicated to DDC SRAM.
In this state, the DDC SRAM can be accessed by
the MCU. The DDC unit does not use the DDC
SRAM when SWENB=1. Since the DDC unit is in
manual mode, the DDC unit generates an MCU
interrupt for each byte transferred. The byte
transferred is held in the I
2
C S1DAT SFR register.
MCU can access DDC SRAM.
