CMP
AVDD and DVDD Comparator Bit.
This is a read-only bit and directly reflects the state of the AVDD and DVDD comparators.
Read “1” indicates that both the AVDD and DVDD supplies are above their selected trip points.
Read “0” indicates that either the AVDD or DVDD supply is below its selected trip point.
5
PSMI
Power Supply Monitor Interrupt Bit.
This bit will be set high by the MicroConverter if CMP is low, indicating low analog or digital
supply. The PSMI bit can be used to interrupt the processor. Once CMPD and/or CMP return
(and remain) high, a 256 ms counter is started. When this counter times out, the PSMI interrupt
is cleared. PSMI can also be written by the user. However, if either comparator output is low,
it is not possible for the user to clear PSMI.

TP2
VDD Trip Point Selection Bits.

PSF
AVDD/DVDD Fault Indicator.
Read “1” indicates that the AVDD supply caused the fault condition.
Read “0” indicates that the DVDD supply caused the fault condition.
0
PSMEN
Power Supply Monitor Enable Bit.
Set to “1” by the user to enable the Power Supply Monitor Circuit.
Cleared to “0” by the user to disable the Power Supply Monitor Circuit.
Example
To configure the PSM for a trip point of 4.37 V, the following
code would be used:
MOV
PSMCON,#005h
;enable PSM with
;4.37V threshold
SETB
EA
;enable interrupts
MOV
IE2,#002h
;enable PSM
;interrupt
If the supply voltage falls below this level, the PC would vector
to the ISR.

;PSMCON.5 is the

JB

;..it is cleared
;only when Vdd
;has remained
;above the trip
;point for 256ms
;or more.
RETI
; return only when "all's well"
SERIAL PERIPHERAL INTERFACE
The ADuC812 integrates a complete hardware Serial Peripheral
Interface (SPI) on-chip. SPI is an industry-standard synchronous
serial interface that allows eight bits of data to be synchronously
transmitted and received simultaneously, i.e., full duplex. It should
be noted that the SPI pins are shared with the I
2C interface, and
therefore the user can only enable one or the other interface at
any given time (see SPE in Table XI). The SPI Port can be con-
figured for Master or Slave operation and typically consists of
four pins, namely:
MISO (Master In, Slave Out Data I/O Pin)
The MISO (master in, slave out) pin is configured as an input
line in master mode and an output line in slave mode. The
MISO line on the master (data in) should be connected to the
MISO line in the slave device (data out). The data is transferred
as byte wide (8-bit) serial data, MSB first.
