TABLE 42: MICROPROCESSOR REGISTER 0XE1H BIT DESCRIPTION
D1
GIE
Global Interrupt Enable
The global interrupt enable is used to enable/disable all interrupt
activity for all 14 channels. This bit must be set "High" for the inter-
rupt pin to operate.
0 = Disable all interrupt generation
1 = Enable interrupt generation to the individual channel registers
R/W
0
D0
SRESET
Software Reset
Writing a "1" to this bit for more than 10S initiates a device reset
for all internal circuits except the microprocessor register bits. To
reset the registers to their default setting, use the Hardware Reset
pin (See the pin description for more details).
