4.6.2 PSS Register
The PSS register permits control over thePSS de-
vice. The register can be addressed in the data
space as a RAM location at DAh. This register is
cleared after Reset.
PSS Status Control Register (PSSCR)
Address: DAh - Read/Write
Bit 7 =
PIF
. Interrupt flagbit. This bit is the interrupt
flag. This bit is set (resp. cleared) as soon as the
equality between nxV
PSS
and mxV
DD
/13 (resp.
(m+1)xV
DD
/13) occurs.
Bit 6 =
PEI
. Interrupt mask bit. This bit is the au-
thorization bit of the interrupt request: – If PEI is
set, the interrupt request can reach the Core. – If
PEI is cleared, the interrupt request cannot reach
the Core.
Bits 5-4 =
PDV1, PDV0
. Division rate selection bit.
The PDV1/0bits are used to select the rate of divi-
sion
of

Bits 3-1 =
PDR2, PDR1, PDR0
. Division rate se-
lection bit. The PDR2/1/0 bits are used to inhibit
the PSS device and to select the division rate of
the PSS voltage (nxV
PSS
/13).
Bit 0 =
D0
. The PSS comparator output is valid 8
cycle times after the programming of the PDR2/1/0
bits. It is forced to zero in the meantime.
