Hi Rob,
It is already very useful, it cought already the first inconsitencies in the
device files.
When i sorted everything by * reg * I noticed that a few T0CON had different
values which did not look correct
When looking for example at the 18f2450,
18F2450 T0CON TMR0ON T08BIT T0CS T0SE T0PS3 T0PS2 T0PS1 T0PS0
This matches with the device file (so wiki is genration is consistent with
device files)
var volatile byte T0CON shared at 0xFD5
var volatile bit T0CON_TMR0ON shared at T0CON : 7
var volatile bit T0CON_T08BIT shared at T0CON : 6
var volatile bit T0CON_T0CS shared at T0CON : 5
var volatile bit T0CON_T0SE shared at T0CON : 4
var volatile bit*4 T0CON_T0PS shared at T0CON : 0
however, the datasheet and the INC file state
bit 7 TMR0ON: Timer0 On/Off Control bit
1 = Enables Timer0
0 = Stops Timer0
bit 6 T08BIT: Timer0 8-Bit/16-Bit Control bit
1 = Timer0 is configured as an 8-bit timer/counter
0 = Timer0 is configured as a 16-bit timer/counter
bit 5 T0CS: Timer0 Clock Source Select bit
1 = Transition on T0CKI pin
0 = Internal instruction cycle clock (CLKO)
bit 4 T0SE: Timer0 Source Edge Select bit
1 = Increment on high-to-low transition on T0CKI pin
0 = Increment on low-to-high transition on T0CKI pin
bit 3 PSA: Timer0 Prescaler Assignment bit
1 = TImer0 prescaler is not assigned. Timer0 clock input bypasses prescaler.
0 = Timer0 prescaler is assigned. Timer0 clock input comes from prescaler
output.
bit 2-0 T0PS2:T0PS0: Timer0 Prescaler Select bits
111 = 1:256 Prescale value
110 = 1:128 Prescale value
101 = 1:64 Prescale value
100 = 1:32 Prescale value
011 = 1:16 Prescale value
010 = 1:8 Prescale value
001 = 1:4 Prescale value
000 = 1:2 Prescale value
;----- T0CON Bits -----------------------------------------------------
T0PS0 EQU H'0000'
T0PS1 EQU H'0001'
T0PS2 EQU H'0002'
PSA EQU H'0003'
T0SE EQU H'0004'
T0CS EQU H'0005'
T08BIT EQU H'0006'
TMR0ON EQU H'0007'
So I don't know how PSA is replaced by T0PS3 in the device file, any ideas?
Noticed the following T0CON irregularities, have not checked if there all
wrong
