8 0 RIC Registers
RIC Register Address Map
The RIC’s registers may be accessed by applying the re-
quired address to the five Register Address (RA(4 0)) input
pins Pin RA4 makes the selection between the upper and
lower halves of the register array The lower half of the reg-
ister map consists of 16 registers
1 RIC Real Time Status and Configuration register
13 Port Real Time Status registers
1 RIC Configuration Register
1 Real Time Interrupt Status Register
54
These registers may be directly accessed at any time via
the RA(4 0) pins (RA4
map (RA4
Event Count Configuration page (0)
Event Record page (1)
Lower Event Count page (2)
Upper Event Count page (3)
Register access within these pages is also performed using
the RA(4 0) pins (RA4
by writing to the Page Selection bits (PSEL2 1 0) These
bits are found in the Page Select Register located at ad-
dress 10 hex on each page of the upper half of the register
array AT power on these bits default to 0 Hex i e page
