DEVICE CONFIGURATION REGISTER SET
The device configuration registers are directly accessible from the bus. This provides easy programming of
general operating parameters to the 798 UART and for monitoring the status of various functions. The device
configuration registers are mapped onto address 0x80-8F as shown on the register map in Table 8 and
. These registers provide global controls and status of all 8 channel UARTs that include interrupt
status, 16-bit general purpose timer control and status, 8X or 16X sampling clock, sleep mode control, soft-
reset control, simultaneous UART initialization, and device identification and revision.
