STFClr
Address:
0x8093_001C - Write
Definition:
Writing to the STFClr location will clear the CLDFLG, WDTFLG and RSTFLG
in the register, “PwrSts” on page 5-14. Any data written to the register triggers
the clearing.
Bit Descriptions:
RSVD:
There are no readable bits in this register.
ClkSet1
Address:
0x8093_0020 - Read/Write
Definition:
The ClkSet1 system control register is one of two register that control clock
speeds.
Note: When a write is performed to the ClkSet1 location, it must be immediately followed by 5
NOP instructions. This is needed to flush the instruction pipeline in the ARM920T core.
Writing to this register will cause the the device to enter Standby for between 8 ms to
16 ms. Reading from this register will not cause an entry into Standby mode.
Bit Descriptions:
RSVD:
Reserved. Unknown During Read.
PLL1_X2IPD:
These 5 register bits set the input divider for PLL1
operation. On power-on-reset the value is set to 00111b (7
decimal).
Note: The value in the register is the actual coefficient minus one.
